TPSM82810: TPSM82810 PG Pin

Derek Wang

Part Number: TPSM82810

Hi,

Could you give me advice if anything I need to correct?

The output voltage is only 0.2V, and PG pin measured result is as below.

Hi Derek,

PG is an open-drain output which requires a pull-up resistor. To get the LED to work properly, move the 1k to be between PG and Vout instead.

As well, you need to place the required output capacitance (27uF effective) before the ferrite beads.
