LTC3355 - 20V 1A Buck DC/DC

General Description

The LTC®3355 is a complete input power interrupt ridethrough DC/DC system.

The part charges a supercapacitor while delivering load current to VOUT, and uses energy from the supercapacitor to provide continuous VOUT backup power when VIN power is lost.
