IRU3072 General Description
The IRU3072 controller IC is designed to provide a low cost synchronous Buck regulator for on-board DC to DC converter for multi-output applications. The outputs can be programmed as low as 0.8V for low voltage applications. The IRU3072 features dual soft-starts which allows power sequencing between outputs.
Over current limit is provided by using external MOSFET's on-resistance for optimum cost and performance. This device features a programmable frequency set from 200KHz to 400KHz, under-voltage lockout for all input supplies, dual external programmable soft-start functions as well as output under-voltage detection that latches off the device when an output short is detected.
