Hello, I am luis

I have questions about TPS65150-Q1.

I try to control TPS65150-Q1 by CTRL pin(pin 13). but TPS65150-Q1 always 4.6V out.

so, would you kike to check my TPS65150-Q1 circuit??

I attach TPS65150-Q1 circuit and Scope waveform(1: ctrl, 2: 4V6 ELVDD)

Hi Luis,

CTRL signal is for the gate voltage shaping, so the VGH is the relevant output rail, not the ELVDD.

Hi ~ then I need to control 4.6_ELVDD on/off. how can I control voltage???

Hi,

This IC doesn't have EN pin, so you need to power off the device to off the ELVDD.
