  • RE: TPS92641: TPS92641 Schematic review & UDIM

    Hi Sheree, For 13A application, you can still take a look at TPS92641 / TPS92640. BR, Steven

  • TPS92641: TPS92641 Schematic review.

    Part Number: TPS92641 Dear TI Team, Request a schematic review of the TPS92641. Input Voltage: DC48V Output Voltage ( LED String Voltage - VLED) : DC45V LED Vf: 3.2V LED Current (ILED) : 7A

  • RE: TPS92641: Use as a Constant Current Capacitor Charger

    Hi Dhruv, Sorry for the delay. We have a discussion on this topic and we think it is possible to use TPS92641 as a constant current regulator to charge capacitor. However, special attention should be paid to overcurrent protection and overvoltage protection…

  • TPS92641: PWP package dimension question

    Part Number: TPS92641 Hi, Our customer's CM is asking for dimension information regarding the TPS92641PWPT/NOPB - the package page seems to lack the relevant information PWP (R-PDSO-G16) 4073225-3 (Rev. A) (ti.com) Could you provide information regarding…

  • TPS92641: High side MOSFET failed

    Part Number: TPS92641 Other Parts Discussed in Thread: CSD18502KCS , CSD18502Q5B Hi, We use the TPS92641 for LED driver chip, the vin is 24V and the LED Vf is 4.6V, LED current is 30A. In current design the MOSFETs of both high side and low side are two…

  • RE: TPS92641: Flicker Problems on TPS02641 using external Shunt FET Dimming

    hi Thomas so you have already tried apply PWM signals both on UDIM and SDIM at the same time? what I mean here is not simply using UDIM for PWM dimming. UDIM acts as enable of TPS92641, pull UDIM down will directly disable gate driver. So I think pull…

  • RE: TPS92641: TPS92641&PMP8016

    Resolved
    hi ray I think the key point is to select a proper mosfet with lower Qg and Rdson. As you know for TPS92641, the gate driver is 1A. Therefore lager Qg will lead to longer rising/falling time to turn on/off Mosfet under the same gate charging current, which…

  • TPS92641: LED Voltag overshoot when PWM turns on

    Resolved
    Part Number: TPS92641 Hi, we have an issue with a TPS92641 design where the voltage on the LED significantly overshoots when the external PWM FET opens and turns on the light. Our schematic is pretty much standard. We chose quite a big inductor in order…
