Part Number: PMP7991 Hello, the reference design PMP7991 shows the development board using the 7508112328 transformer as part of fly-back conversion. However, your WEBENCH tool output circuit design based on same circuit characteristics do match transformer…
Part Number: TPS25946 Hi,
I have a customer using TPS25946, there are some problems, please help to support!
Required functions: Type-C uses 24Pin model: CX90B2_24P, VBUS isolation protection circuit design is as follows (chip TPS25946) : (No charging…
Part Number: LMR14050 Hi,
1. Could LMR14050 output stable 0.1 - 5A for all Vout range (0.75 - 38V)?
2. In webench design, some Vin, Vout and Iout combinations are invalid. Where can I get the error message so that I could figure out the root cause and…
Kazuki Itoh said: Could you please comment on the updated output capacitance and SS?
The MODE resistor is selecting 2ms soft-start. With 2,840μF of output capacitance at 0.75V, that will require just over 1A of charging current, well within the design…
Hi Brian, I ended up going with values closer to the webench results. We have a design in production for a long time that seems to be similar to that compensation circuit.

Part Number: DRV8301
Hi Team,
The customer is wondering why the below 2 designs are not included in the recommended design of the datasheet and the development board:
1) The gate resistor provides a low-resistance bleed-off path for the shutdown current…
