† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: The THS3122 and THS3125 may incorporate a PowerPAD on the underside of the chip. This acts as a heatsink and must be connected to a thermally dissipating plane for proper power dissipation. Failure to do so may result in exceeding the maximum junction temperature which could permanently damage the device.

Each switch is disabled when the associated output-enable (OE) input is high.This device is fully specified for partial-power-down applications using I off . The I off feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off.To ensure the high-impedance state during power up or power down, OE should be tied to V CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.ORDERING INFORMATIONT APACKAGE †ORDERABLE PART NUMBER TOP-SIDE MARKING QFN − RGY Tape and reel SN74CBTLV3125RGYR CL125Tube SN74CBTLV3125D SOIC − DTape and reel SN74CBTLV3125DR CBTLV3125°°SOP − NSTape and reel SN74CBTLV3125NSR CBTLV3125−40C to 85CSSOP (QSOP) − DBQ Tape and reel SN74CBTLV3125DBQR CL125TSSOP − PW Tape and reel SN74CBTLV3125PWR CL125TVSOP − DGVTape and reelSN74CBTLV3125DGVRCL125†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at /sc/package.Copyright 2003, Texas Instruments IncorporatedPRODUCTION DATA information is current as of publication date.Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.SN74CBTLV3125LOWĆVOLTAGE QUADRUPLE FET BUS SWITCHSCDS037J − DECEMBER 1997 − REVISED OCTOBER 2003FUNCTION TABLE(each bus switch)INPUTOEFUNCTIONL A port = B portH Disconnectlogic diagram (positive logic)1A1OESW1B2A2OESW2B3A3OESW3B4A 4OESW4B 2154369101213811Pin numbers shown are for the D, DGV, NS, PW, and RGY packages.simplified schematic, each FET switchA(OE)BSN74CBTLV3125LOWĆVOLTAGE QUADRUPLE FET BUS SWITCHSCDS037J − DECEMBER 1997 − REVISED OCTOBER 2003 absolute maximum ratings over operating free-air temperature range (unless otherwise noted)†Supply voltage range, V CC−0.5 V to 4.6 V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Input voltage range, V I (see Note 1) −0.5 V to 4.6 V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Continuous channel current 128 mA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Input clamp current, I IK(V I/O< 0) −50 mA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Package thermal impedance, θJA(see Note 2):D package 86°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .(see Note 2):DBQ package 90°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .(see Note 2):DGV package 127°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .(see Note 2):NS package 76°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .(see Note 2):PW package 113°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .(see Note 3):RGY package 47°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Storage temperature range, T stg −65°C to 150°C. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .†Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.

DescriptionThe AP3125A/V/L/R is a current mode PWM controller which is optimized for high performance, low standby power and cost effective offline flyback converters.The PWM switching frequency at normal operation is internally fixed (about 65kHz). In middle load, the IC will enter green mode to improve system efficiency with the help of frequency foldback. A minimum switching frequency (about 20kHz) is set to avoid the audible noise. In no load or light load, the IC will enter the burst mode to minimize standby power. Furthermore, the frequency dithering function is built-in to reduce EMI emission.Internal slope compensation allows more stable Peak-Current Mode control over wide range of input voltage and load conditions. Internal line compensation ensures constant output power limit over entire universal line voltage range.Comprehensive protection features are included, such as cycle-by-cycle current limit (OCP), VCC Over Voltage Protection (VOVP), internal OTP, Over Load Protection (OLP) and pins ’ fault protection. The versatile latch functions can be implemented using a minimal number of external components.Features∙ Very Low Start-up Current ∙ Current Mode Control∙ Non-audible-noise Green-mode Control ∙ Internal Slope Compensation ∙ Soft Start During Startup Process∙ Frequency Fold Back for High Average Efficiency ∙ Secondary Winding Short Protection with FOCP ∙ Soft Switching for Reducing EMI ∙ VCC Maintain Mode∙Useful Pin Fault Protection: SENSE Pin FloatingCTRL Pin Short to Ground FB/Opto-coupler Open/Short∙Comprehensive System Protection Feature: VCC Over Voltage Protection (VOVP) Over Load Protection (OLP)∙ Optional Latch Mode for VOVP, OLP and CTRL Pin Protection ∙ Mini Size Package of SOT26∙ Pin to Pin Compatible with AP3105NA/NV/NL/NR∙ Totally Lead-free & Fully RoHS Compliant (Notes 1 & 2) ∙ Halogen and Antimony Free. “Green ” Device (Note 3)Pin Assignments(Top View)SOT26Applications∙ Switching AC-DC Adapter/Charger ∙ ATX/BTX Auxiliary Power∙ Set-top Box (STB) Power Supply∙ Open Frame Switching Power SupplyNotes: 1.

It offers a cost effective solution with a versatile protection function.Start-up Current and UVLOThe start-up current of AP3125A/V/L/R is optimized to realize ultra low current (1m A typical) so that VCC capacitor can be charged more quickly. The direct benefit of low start-up current is the availability of using large start-up resistor, which minimizes the resistor power loss for high voltage AC input.An UVLO comparator is included in AP3125A/V/L/R to detect the voltage on VCC pin. It ensures that AP3125A/V/L/R can draw adequate energy from hold-up capacitor during power-on. The turn-on threshold is 16V and the turn-off threshold is 7.6V.Current Sense Comparator and PWM LatchThe AP3125A/V/L/R operates as a current mode controller, the output switch conduction is initiated by every oscillator cycle and is terminated when the peak inductor current reaches the threshold level established by the FB pin. The inductor current signal is converted to a voltage signal by inserting a reference sense resistor R S . The inductor current under normal operating conditions is controlled by the voltage at FB pin. The relation between peak inductor current (I PK ) and V FB is:SFB PK R V I 3/)8.0(-=Moreover, FOCP with 1.8V threshold is only about 100ns delay, which can avoid some catastrophic damages such as secondary rectifier short test. Few drive cycles can alleviate the destruction range and get better protection.Leading-edge BlankingA narrow spike on the leading edge of the current waveform can usually be observed when the power MOSFET is turned on. A 250ns leading-edge blank is built-in to prevent the false-triggering caused by the turn-on spike. During this period, the current limit comparator is disabled and the gate driver can not be switched off.At the time of turning off the MOSFET, a negative undershoot (maybe larger than -0.3V) can occur on the SENSE pin. So it is strongly recommended to add a small RC filter or at least connect a resistor “R” on this pin to protect the IC (Shown as Figure 1).Figure 1It is well known that a continuous current mode SMPS may become unstable when the duty cycle exceeds 50%. The built-in slope compensation can improve the stability, so there is no need for design engineer to spend much time on that.FB Pin and Short Circuit ProtectionThis pin is normally connected to the opto-coupler and always paralleled with a capacitor for loop compensation. When the voltage at this pin is greater than 4.5V and lasts for about 70ms, the IC will enter the protection mode. For AP3125A/V/L/R, the system will enter hiccup mode to wait the V CC decreasing to low UVLO level, then the IC will try to restart until the failure removed. And when this voltage is less than 1.55V, the IC will stop the drive pulse immediately. Therefore, this feature can be used for short circuit protection, which makes the system immune from damage. Normally, output short makes the V FB value to the maximum because the opto-coupler is cut off.V CC Maintain ModeDuring light load or step load, V FB will drop and be lower than 1.55V, thus the PWM drive signal will be stopped, and there is no more new energy transferred due to no switching. Therefore, the IC supply voltage may reduce to the shutdown threshold voltage and system may enter the unexpected restart mode. To avoid this, the AP3125A/V/L/R hold a so-called V CC maintain mode which can supply energy to VCC.When V CC decreases to a setting threshold, the V CC maintain comparator will output some drive signal to make the system switch and provide a proper energy to VCC pin. The V CC maintain function will cooperate with the PWM and burst mode loop which can make the output voltage variation be within the regulation. This mode is very useful for reducing startup resistor loss and achieving a better standby performance with a low value VCC capacitor. The V CC is not easy to touch the shutdown threshold during the startup process and step load. This will also simplify the system design. The minimum VCC voltage is suggested to be designed a little higher than V CC maintain threshold thus can achieve the best balance between the standby and step load performance 。
