Description

The IRU3137 controller IC is designed to provide a low cost and high performance synchronous Buck regulator for on-board DC to DC converter applications. The output voltage can be set as low as 0.8V and higher voltage can be obtained with an external voltage divider. High peak current gate drivers provide fast switching transition for applications requiring high output current in the range of 15A to 20A.

This IRU3137  features an internal 200KHz oscillator, under- voltage lockout for both Vcc and Vc supplies, an external programmable soft-start function as well as output under-voltage detection that latches off the device when an output short is detected.
