OB2532A
高精度原边 PWM 电源开关器
工作原理概述
OB2532A 是一款低系统成本的 LED 驱动控制 器，芯片工作在不连续（DCM）模式，应用于反 激隔离 LED 照明。采用原边反馈控制技术，无 需 TL431 和光耦等二次侧元器件， 其内置专利的 恒流（CC）控制技术，可以实现高精度的 LED 恒流输出特性，满足 LED 照明应用。 启动电流和启动控制 OB2532A 优化设计了启动电流（Typ. 5uA） ，当 VDD 电压经充电高于 UVLO（OFF）阈值电压， 芯片可以很快开启工作，因此在系统板上可以使 用高阻值的启动电阻来减小功率损耗。 工作电流 OB2532A 低至 2mA 的工作电流和多模式控制方 式可以实现系统的高转换效率和低待机功耗。 软启动 系统上电后，OB2532A 的内部软启动功能可以 减小 LED 电流过冲， 当 VDD 电压经充电高于 UVLO（OFF）阈值电压，芯片内部算法控制 CS 引脚峰值电压逐渐从 0V 增加到 0.8V，每次重启 都有软启动。 CC 工作原理 OB2532A 专利的 CC 控制需要工作在不连续模 式，应用于反激隔离 LED 照明(参考第 1 页典型 应用图)。LED 输出电流 Iout 计算公式： TDemag 与原边绕组电感量成反比例，控制 Lp 和开 关频率的乘积恒定不变，这样输出电流就不随原边 电感量的变化而变化。 芯片最大补偿原边电感量± 7% 偏差变化，实现 LED 恒流输出。 LED 输出电流计算公式：

Position the load between 50 mm and 75 mm from the DC/DC Converter.Remote On/OffPositive logic remote on/off turns the module on during a logic high voltage on the remote on/off pin, and off during a logic low.To turn the power module on and off, the user must supply a switch to control the voltage between the on/off terminal and the -Vin terminal.The switch can be an open collector or equivalent.A logic low is -0.7V to 0.8V.A logic high is 2.5V to 5.5V.The maximum sink current at on/off terminal during a logic low is -1 mA.The maximum allowable leakage current of the switch at on/off terminal (2.5 to 5.5V) is 50uA.Overcurrent ProtectionTo provide protection in a fault (output overload) condition,the unit is equipped with internal current limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from voltage control to current control. The unit operates normally once the output current is brought back into its specified range.Input Source ImpedanceThe power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the power module.In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor at the input to ensure startup.Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0[ at 100KHz) capacitor of a 22uF for the 12V input devices and a 6.8uF for the 24V and 48V devices.MKW2500 Series6MINMAXREV:0 2005/04Output Ripple ReductionA good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance.To reduce output ripple, it is recommended to use 4.7uF capacitors at the output.Maximum Capacitive LoadThe MKW2500 series has limitation of maximum connected capacitance at the output.The power module may be operated in current limiting mode during start-up, affecting the ramp-up and the startup time.For optimum performance we recommend 220uF maximum capacitive load for dual outputs and 470u F capacitive load for single outputs.The maximum capacitance can be found in the data sheet.Thermal ConsiderationsMany conditions affect the thermal performance of the power module, such as orientation, airflow over the module and board spacing. To avoid exceeding the maximum temperature rating of the components inside the power module, the case temperature must be kept below 100°C.The derating curves are determined from measurements obtained in an experimental apparatus.MKW2500 SeriesREV:0 2005/04MINMAX7The MKW2500 converter is encapsulated in a low thermal resistance molding compound that has excellent resistance/electrical characteristics over a wide temperature range or in high humidity environments.The encapsulant and unit case are both rated to UL 94V-0 flammability specifications.Leads are tin plated for improved solderability.UL94V-0:FlammabilityRemote On/Off (Optional)632g :Weight -Vout-Vout5Common No Pin 4Metal With Non-Conductive Baseplate :Case Material +Vout +Vout 3-Vin -Vin 2 2.0*1.0*0.4 inches+Vin +Vin 150.8*25.4*10.2 mm :Case Size Dual OutputSingle OutputPin Physical CharacteristicsPin Connections{0.002{0.05PinX.XXX{0.005X.XX{0.13Connecting Pin PatternsMechanical DimensionsMKW2500 Series8MINMAX REV:0 2005/04。
OB2532
总体描述：OB2532是一个应用于低功率AC/DC充电器和适配器的高性能离线式PWM 控制器。
它工作在初级检测与调节。
因此，可省去光耦和TL431。
并且集成了专有的恒压恒流控制，如下图所示。
在恒流控制中，电流和功率的设定可以通过CS脚上的Rs电阻来外部调节。
在恒压控制中，采用多模式操作来达到高性能和高效率。
另外，可以通过内部电缆压降补偿完成好的负载调整。
在恒流模式并且大负载条件下，器件工作于PFM 模式，而在轻/中负载时，随着频率的降低，器件工作于PWM模式。
OB2532提供的保护功能有软启动和自动重起动、逐周期流限、VDD过压保护、VDD拑位和欠压锁定保护。
集成了On-bright公司专有的频率抖动技术使器件具有优良的EMI性能。

恒流驱动芯片
3 LED 恒流驱动芯片之二:原边控制的PWM 控制器OB2532OB2532 是一种高性能的脱机PWM 控制器，输出功率低于15W，可以用作低功率的AC /DC 充电器和适配器，如手机、数码相机的充电器，PC 机和电视的辅助电源。
采用SOT23－ 6 封装，有6 条引脚。
由于反馈控制来自原边，不存在隔离问题，因而无需像Viper12A /22A 那样，要用到光耦和稳压器TL431( 在图3 中使用了光耦H11AB17A 及双运放和基准电压TSM103) ，线路连接比较简单。
3. 1 驱动电路的特点(1) 全电压范围内有± 5% 的恒流调整精度，输出电流可以调节，可以设定输出功率;(2) 在原边控制下的副边恒流控制;(3) 自适应的峰值电流控制;(4) 内部有对原边绕组的电感补偿;(5) 可以对恒流及恒压值进行调整;(6) 电源接通时有软启动功能;(7) 电流检测有前沿消隐功能( LEB) ，无需外接滤波电路;(8) 能逐周对电流进行限制;(9)VDD 有欠电压封锁功能，且有回差。
OB2532 同Viper12A /22A 一样，也具有恒压(CV) 及恒流(CC) 输出特性，其特性可以用图8 的矩形曲线表示。
图8 OB2532 的输出矩形特性在恒流(CC) 控制下，输出功率可以通过CS 脚外接电阻RS( 也是MOS 管的源极电阻) 来调节;在恒压(CV) 控制下，为达到高效和提高性能的目的，可以有多种工作模式。
此外，由于内部有1 个对电缆压降进行补偿的线路，可以使负载具有很好的调整特性。
器件在恒流模式及大负载下，工作于脉频调制( PFM) 方式，而在轻负载/ 中等负载下，则降低频率，并工作于脉宽调制( PWM) 方式。
3. 2 OB2532 的引脚符号及功能它共有6 条引脚，其名称及功能如下:(1)GND———地;(2) GATE———为图腾柱输出，用来驱动外接的MOS 管;(3)CS———电流监测输入端，连到MOS 管源极的检测电阻上;(4) INV———误差放大器EA 的反相输入端，由变压器辅助绕组送来的反馈电压经电阻分压加于此端，它反映输出电压的大小，PWM 占空比取决于误差放大器EA 的输出及3 脚的电流监测信号;(5) COMP———EA 放大器的补偿端，接补偿电容，以使恒压输出保持稳定;(6)VDD———IC 的电源。

This document covers a description of the EM board and its features and a brief tutorial on how to operate the module EM board.1.2 Applicable Documents∙TiWi-uB2 Datasheet (330-0100)∙TiWi-uB2 Antenna Design Guide (330-0106)1.3 Revision HistoryTable 1 Revision History2TiWi-uB2 Module DescriptionThe TiWi-uB2 EM “Evaluation Module” Board is an evaluation platform for the LSResearch TiWi-uB2 Bluetooth and Bluetooth Low Energy (BLE) module.Communication between the TiWi-uB2 module, which is a slave, and the host device is through a UART interface.The TiWi-uB2 EM Board contains an on board chip antenna and U.FL connector. The EM board is intended for evaluation purposes when used in conjunction with variousTexas Instruments MSP430 and Stellaris development boards.Figure 1 TiWi-uB2 EM Board TopFigure 2 TiWi-uB2 EM Board Bottom3 TiWi-uB2 EM Board Hardware 3.1 AntennaThe TiWi-uB2 EM Board contains an on board chip antenna which is modular certified for FCC 15.247 and IC RSS-210, as well as compliant to the RF requirements for ETSI EN 300 328 and ETSI EN 301 489. The antenna layout and circuitry on the EM Board can be replicated on a custom designed PCB assembly. Assuming the design/layout is followed exactly as that which is on the EM Board, the custom PCB will retain the modular certification. Below are details on the certifications.FCC ID: TFB-BT1, 15.247 IC ID: 5969A-BT1, RSS 2103.2 ConnectorsThere are two primary connectors on the TiWi-uB2 EM Board (J1 & J2). These provide a standard interface to Texas Instruments development platforms (See Section 3.9). Two additional non populated connectors (J4 & J5) provide access to all of the significant signals on the module on a standard, single row 2mm pitch header.165423789Figure 3 TiWi-uB2 EM Board Top Side ConnectorsTable 2 TiWi-uB2 EM Board Top Side Connectors3.3 Required Signals between EM Board and Host DeviceIn addition to power and ground, there are three signals required for connecting a TiWi-uB2 module to a host device. See Table 3 below for details on these connections.Table 3 TiWi-uB2 Required Connections3.4 Connecting EM Board to Host PlatformThe TiWi-uB2 EM Board is intended to allow for evaluation of and early developmentwith a TiWi-uB2 module. The EM Board has two “EM” connectors on the bottom of the board that allows for easy connection to various Texas Instruments microcontrollerdevelopment platforms. The primary development platform is the MSP430F5438Experimenter Board.It is also possible to adapt the TiWi-uB2 EM Board to work with microcontroller platforms that do not have support for the EM connectors. Sections 3.9 and 3.10 describe the two options for adapting an EM Board to work with other microcontroller platforms.3.5 Power Supply3.5.1 VBATVBAT requires a 3.0V to 4.8V DC power supply.3.5.2 VDD_IOVDD_IO requires a 1.8V DC power supply.Figure 4 Power Supply3.6 Serial InterfacesThere are two serial interfaces to the module, HCI UART and PCM. Each interface isdescribed below.Figure 5 Serial Interfaces3.7 HCI UARTThis is the main interface between the host microcontroller and the module. TheBluetooth UART may also be used to download external patches from the host to theTiWi-uB2. The UART interface supports baud rates from 9600bps to 4Mbps.BT debug pin: The debug interface (TX_DBG) helps customers to debug the HW/SWissues for their application (not pictured).3.8 PCM InterfaceThe PCM Interface can connect to linear PCM Codec devices in master or slave mode.In master mode, the TiWi-uB2 generates the PCM_CLK and PCM_SYNC signals, and in slave mode, these signals are provided by another master on the PCM interface and are inputs to the TiWi-uB2.Figure 6 PCM Interface3.9 Option 1: Using EM ConnectorsEither build a PCB which has the EM Board mating connectors which will allow forplugging the TiWi-uB2 EM Board into, or solder wires to EM Board mating connectorsthat can then be wired into whatever development platform is being used.Below are two suggestions for the mating EM connectors.Through hole connector: Samtec TFM-110-01-S-D-WTSurface Mount connector: Samtec SFM-110-02-L-D-AIf building a PCB that has the mating EM Board connectors, the connectors need to be lined up and spaced 1.2” apart as shown in Figure 7.Figure 7 Host PCB EM Mating Connector Arrangement (Top View)Refer to Table 4 and Table 5 below for details on the signals brought out to the EM connectors J1 and J2.Table 4 EM Connector J1Table 5 EM Connector J2DI = Digital Input; DO = Digital Output; DIO = Digital Input/Output; PI = Power Input3.10 Option 2: Using Single Row HeadersSolder single row 12 pin 2mm headers into locations J4 and J5 on the EM Board, and then build a wiring harness between the headers on the EM Board and themicrocontroller development platform of interest.Below is a suggestion for the 12 pin 2mm headers.Sullins NRPN121PAEN-RCRefer to Table 6 and Table 7 below for details on the signals brought out to the single row headers J4 and J5.Table 6 Single Row Header J4DI = Digital Input; DO = Digital Output; PI = Power InputTable 7 Single Row Header J5DI = Digital Input; DO = Digital Output; DIO = Digital Input/Output; PI = Power Input3.11 Using J7 with USB to Serial ConverterJ7 is provided for interfacing the TiWi-uB2 Module to a USB-to-Serial converter, or similar serial device capable of providing 1.8V logic level data.Table 8 Single Row Header J7DI = Digital Input; DO = Digital Output; DIO = Digital Input/Output; PI = Power Input;4.1 Bill Of Material (BOM)Table 9 TiWi-uB2 EM Board BOM5Application Development5.1 OverviewThe TiWi-uB2 EM Board used in conjunction with a Bluetooth stack running on TI’sMSP430BT5438 or Stellaris LM3S9B96microcontroller (MCU) will reduce designbarriers and provides a highly flexible platform to enable customer’s early prototyping capabilities of embedded Bluetooth applications.
