Part Number: LM51571-Q1 Hello,
We’re currently working on the worst-case analysis of the LM51571-Q1, and to complete the analysis we kindly request the following information:
Total gate charge (Qg) of the integrated power MOSFET.
The rise…
Part Number: LM51571-Q1 Other Parts Discussed in Thread: DRV2911-Q1 Hi.
I'm using an LM51571-Q1 to supply the PVDD of the DRV2911-Q1. The DRV2911-Q1's output is connected to a piezo, and when outputting the piezo's resonant frequency, the PVDD drops…

Your webench site I find LM51571 to use for booster 24Vin->40Vout 350mA
Wich pin I can use for dimmer command for variable Iout with PWM signal ?
Thank…
Part Number: LM51571-Q1 Tool/software: Hi! I have designed in webench and made a prototype PCB for a boost DC/DC converter based on the LM51571Q. And it is overheating at 200 mA load but it was designed for 1 A loads. At loads higher than 200 mA the schottky…

Part Number: LM51571-Q1 Tool/software: Hello,
Currently trying to use boost power management device, LM51571-Q1 with an input voltage of 24V and boosting to 26V. We have the following circuit:
However, we are observing a 1-1.2V ripple on the output…
Part Number: LM51571-Q1 Hi,
I tried the boost design typ. 5V to 48V for I_load = 0.05A at the lowest fsw possible.
Webench selects 6.8uH @ fsw=0.305MHz:
I think L=6.8uH is too low... In fact, excel sheet recommends 60.980uH or more:
Could…

I'm trying to use LM51571-Q1 to supply PVDD power to DRV2911-Q1.
Please review the circuit.
Tank you.
Part Number: LM51571-Q1 Tool/software: Dear TI experts,
My customer drew their first schematic with LM51571-Q1. Could you review this schematic?
(Input is car battery, Output is 35V / 1A.)
Best regards,
Chase
