What is a tps53219a?
7.1 Overview The TPS53219A is a high-efficiency, single-channel, synchronous buck regulator controller suitable for low output voltage point-of-load applications in computing and similar digital consumer applications.
What is a tps53219a Buck regulator?
The TPS53219A is a high-efficiency, single-channel, synchronous buck regulator controller suitable for low output voltage point-of-load applications in computing and similar digital consumer applications.
Why does the tps53219a pull up to VREG when powered up?
before the TPS53219A is powered up, TI recommends that the PGOOD pin be pulled up to VREG (either directly or through a resistor divider if a different pullup voltage is desired) because VREG remains low when the device is powered off.
