All rights reserved. is a registered trademark of Richtek Technology Corporation.Application InformationThe basic RT8055 application circuit is shown in TypicalApplication Circuit. External component selection is determined by the maximum load current and begins with the selection of the inductor value and operating frequency followed by C IN and C OUT .Output Voltage SettingThe output voltage is set by an external resistive divider according to the following equation :Figure 1. Setting the Output Voltage⎟⎠⎞⎜⎝⎛+×=R2R11V V REF OUT Soft-StartThe RT8055 contains an internal soft-start clamp that gradually raises the clamp on the COMP pin.Operating FrequencySelection of the operating frequency is a tradeoff between efficiency and component size. High frequency operation allows the use of smaller inductor and capacitor values.Operation at lower frequency improves efficiency by reducing internal gate charge and switching losses but requires larger inductance and/or capacitance to maintain low output ripple voltage.The operating frequency of the RT8055 is determined by an external resistor that is connected between the SHDN/RT pin and GND. The value of the resistor sets the ramp current that is used to charge and discharge an internal timing capacitor within the oscillator. The RT resistor value can be determined by examining the frequency vs. R RT curve. Although frequencies as high as 2MHz are possible,the minimum on-time of the RT8055 imposes a minimum limit on the operating duty cycle. The minimum on-time is typically 110ns. Therefore, the minimum duty cycle is equal to 100 x 110ns x f (Hz).Figure 2100% Duty Cycle OperationWhen the input supply voltage decreases toward the outputvoltage, the duty cycle increases toward the maximum on-time. Further reduction of the supply voltage forces the main switch to remain on for more than one cycle eventually reaching 100% duty cycle.The output voltage will then be determined by the input voltage minus the voltage drop across the internal P-MOSFET and the inductor.Low Supply OperationThe RT8055 is designed to operate down to an input supply voltage of 2.6V. One important consideration at low input supply voltages is that the R DS(ON) of the P-Channel and N-Channel power switches increases. The user should calculate the power dissipation when the RT8055 is used at 100% duty cycle with low input voltages to ensure that thermal limits are not exceeded.Slope Compensation and Inductor Peak Current Slope compensation provides stability in constant frequency architectures by preventing sub-harmonic oscillations at duty cycles greater than 50%. It is accomplished internally by adding a compensating ramp to the inductor current signal. Normally, the maximum inductor peak current is reduced when slope compensation is added. In the RT8055, however, separated inductor current signals are used to monitor over current condition.0.00.51.01.52.02.53.002004006008001000R OSC (K )S w i t c h i n g F r e q u e n c y (M H z )(k Ω)where V REF equals to 0.8V typical.The resistive divider allows the FB pin to sense a fraction of the output voltage as shown in Figure 1.RT8055©Copyright 2012 Richtek Technology Corporation. All rights reserved. is a registered trademark of Richtek Technology Corporation.This formula has a maximum at V IN = 2V OUT , where I RMS = I OUT /2. This simple worst-case condition is commonly used for design because even significant deviations do not offer much relief. Choose a capacitor rated at a higher temperature than required.Several capacitors may also be paralleled to meet size or height requirements in the design.The selection of C OUT is determined by the effective series resistance (ESR) that is required to minimize voltage ripple and load step transients, as well as the amount of bulk capacitance that is necessary to ensure that the control loop is stable. Loop stability can be checked by viewing the load transient response as described in a later section.The output ripple, ΔV OUT , is determined by :1V V V V I I OUTININ OUT OUT(MAX)RMS −=⎦⎤⎢⎣⎡+Δ≤ΔOUT L OUT 8fC 1ESR I V This keeps the maximum output current relatively constant regardless of duty cycle.Short Circuit ProtectionWhen the output is shorted to ground, the inductor current decays very slowly during a single switching cycle. A current runaway detector is used to monitor inductor current. As current increasing beyond the control of current loop, switching cycles will be skipped to prevent current runaway from occurring.Inductor SelectionThe inductor value and operating frequency determine the ripple current according to a specific input and output voltage. The ripple current ΔI L increases with higher V IN and decreases with higher inductance.OUT OUT L IN V V I =1f L V ⎡⎤⎡⎤Δ×−⎢⎥⎢⎥×⎣⎦⎣⎦OUT OUT L(MAX)IN(MAX)V V L =1f I V ⎡⎤⎡⎤×−⎢⎥⎢×Δ⎣⎦⎣⎦Having a lower ripple current reduces not only the ESR losses in the output capacitors but also the output voltage ripple. However, it requires a large inductor to achieve this goal.For the ripple current selection, the val ue of ΔI L = 0.4(I MAX )will be a reasonable starting point. The large st ripple current occurs at the highest V IN . To guarantee that the ripple current stays below the specified maximum, the inductor value should be chosen according to the following equation :The inductor's current rating (caused a 40°C temperature rising from 25°C ambient) should be greater than the maximum load current and its saturation current should be greater than the short circuit peak current limit.C IN and C OUT SelectionThe input capacitance, C IN , is needed to filter the trapezoidal current at the source of the top MOSFET . To prevent large ripple voltage, a low ESR input capacitor sized for the maximum RMS current should be used. RMS current is given by :The output ripple is highest at maximum input voltagesince ΔI L increases with input voltage. Multiple capacitors placed in parallel may be needed to meet the ESR and RMS current handling requirements. Dry tantalum, special polymer, aluminum electrolytic and ceramic capacitors are all available in surface mount packages. Special polymer capacitors offer very low ESR but have lower capacitance density than other types. Tantalum capacitors have the highest capacitance density but it is important to only use types that have been surge tested for use in switching power supplies. Aluminum electrolytic capacitors have significantly higher ESR but can be used in cost-sensitive applications provided that consideration is given to ripple current ratings and long term reliability. Ceramic capacitors have excellent low ESR characteristics but can have a high voltage coefficient and audible piezoelectric effects.The high Q of ceramic capacitors with trace inductance can also lead to significant ringing.Using Ceramic Input and Output CapacitorsHigher values, lower cost ceramic capacitors are now becoming available in smaller case sizes. Their high ripple current, high voltage rating and low ESR make them ideal for switching regulator applications. However, care must be taken when these capacitors are used at the input and output. When a ceramic capacitor is used at the inputDS8055-05 November 2012©Copyright 2012 Richtek Technology Corporation.

At best, this ringing can couple to the output and be mistaken as loop instability. At worst, a sudden inrush of current through the long wires can potentially cause a voltage spike at V IN large enough to damage the part.Thermal ConsiderationsFor continuous operation, do not exceed absolute maximum junction temperature. The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula :P D(MAX) = (T J(MAX) − T A ) / θJAwhere T J(MAX) is the maximum junction temperature, T A is the ambient temperature, and θJA is the junction to ambient thermal resistance.For recommended operating condition specifications, the maximum junction temperature is 125°C. The junction to ambient thermal resistance, θJA , is layout dependent. For SOP-8 (Exposed Pad) packages, the thermal resistance,θJA , is 75°C/W on a standard JEDEC 51-7 four-layer thermal test board. For WDFN-10L 3x3 packages, the thermal resistance, θJA , is 70°C/W on a standard JEDEC 51-7 four-layer thermal test board. The maximum power dissipation at T A = 25°C can be calculated by the following formulas :P D(MAX) = (125°C − 25°C) / (75°C/W) = 1.333W for SOP-8 (Exposed Pad) packageP D(MAX) = (125°C − 25°C) / (70°C/W) = 1.429W for WDFN-10L 3x3 packageThe maximum power dissipation depends on the operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA . The derating curves in Figure 3 allow the designer to see the effect of rising ambient temperature on the maximum power dissipation.Figure 3. Derating Curve of Maximum Power Dissipation Layout ConsiderationsFollow the PCB layout guidelines for optimal performance of RT8055.`A ground plane is recommended. If a ground plane layer is not used, the signal and power grounds should be segregated with all small-signal components returning to the GND pin at one point that is then connected to the PGND pin close to the IC. The exposed pad should be connected to GND.`Connect the terminal of the input capacitor(s), C IN , as close as possible to the PVDD pin. This capacitor provides the AC current into the internal power MOSFETs.`LX node is with high frequency voltage swing and should be kept within small area. Keep all sensitive small-signal nodes away from the LX node to prevent stray capacitive noise pick-up.`Flood all unused areas on all layers with copper.Flooding with copper will reduce the temperature rise of powercomponents.You can connect the copper areas to any DC net (PVDD,VDD, VOUT , PGND, GND, or any other DC rail in your system).`Connect the FB pin directly to the feedback resistors.The resistor divider must be connected between V OUT and GND.0.00.10.20.30.40.50.60.70.80.91.01.11.21.31.41.50255075100125Ambient Temperature (°C)M a x i m u m P o w e r D i s s i p a t i o n (W )©Copyright 2012 Richtek Technology Corporation.

ldo 负电源转换

ldo 负电源转换

ldo 负电源转换LDO 负电源转换引言:LDO(低压差线性稳压器)是一种常见的电源管理器件,用于将高电压输入转换为稳定的低电压输出。

本文将重点介绍LDO 负电源转换的原理和应用。

一、LDO 负电源转换的原理LDO 负电源转换使用了负反馈控制的稳压技术,通过反馈电路将输出电压与参考电压进行比较,然后调节输出电压以使其稳定在设定值。

具体来说,LDO 负电源转换器由输入电源、稳压电路和输出负载组成。

1. 输入电源:输入电源通常为高电压直流电源,其电压范围可以从几伏到几十伏不等。

输入电源通过输入引脚输入到稳压电路中。

2. 稳压电路:稳压电路是LDO 负电源转换的核心部分,其通过反馈电路控制输出电压的稳定性。

稳压电路通常由一个参考电压源、一个误差放大器和一个功率放大器组成。

- 参考电压源:参考电压源是稳压电路的基准,其输出电压稳定且温度系数低,以提供给误差放大器作为比较基准。

- 误差放大器:误差放大器将输出电压与参考电压进行比较,并将比较结果放大后输出给功率放大器。

当输出电压偏离设定值时,误差放大器会产生一个控制信号。

- 功率放大器:功率放大器根据误差放大器的控制信号,调节输出电压以使其稳定在设定值。

功率放大器通常由一个或多个晶体管组成,通过调节负载电流来实现电压调节。

3. 输出负载:输出负载是LDO 负电源转换的目标,其可以是各种电子设备,如微处理器、存储器等。

输出负载通过输出引脚连接到稳压电路,从而获得稳定的电压供电。

二、LDO 负电源转换的应用LDO 负电源转换广泛应用于各种电子设备和系统中,以下是几个常见的应用场景:1. 电子产品:LDO 负电源转换器常用于手机、平板电脑、数码相机等电子产品中,用于提供稳定的电压给各个组件和模块。

2. 通信系统:通信系统中有许多对电压稳定性要求较高的模块,如射频模块、基带模块等。

LDO 负电源转换器可以提供稳定的电压给这些模块,以保证通信质量和性能。

3. 工业控制:在工业控制系统中,LDO 负电源转换器可用于给传感器、执行器和其他控制模块提供稳定的电源。
