Hi TI,
For the TPS621361 chip, I want to enable this supply from a system on a module that outputs a 3V3 signal via GPIO. All documentation for this chip suggests always tying it to the Vinput line. With the implementation I'm seeking, a GPIO 3v3 signal would go into the EN pin, and there'd be a 1meg pull-down on the pin to assert a logic low when the GPIO is off. Would there be an issue with this configuration?
Hi,
You can use external signal to control EN not only connect it to Vin with resistors.
Thanks!
