MAX16920BATJ/V+

Product Summary

The MAX16920BATJ/V+ is a kind of power-management IC which integrates three high-voltage step-down DC-DC converters, one high-voltage linear regulator, and an overvoltage protection block.The MAX16920BATJ/V+ is designed to operate with input voltages between 5.5V to 28V and survive voltage transients to 45V, making it ideal forautomotive applications.The MAX16920BATJ/V+ includes power-good outputs (PG_) for DC-DC2, DC-DC3, LDOA, and a power-on reset (POR) for DC-DC1. The MAX16920BATJ/V+ is widely used in automotive radios and automotive navigation systems.
