LTC3355 Datasheet (Linear) - 20V 1A Buck DC/DC

LTC3355, 20V 1A Buck DC/DC

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.

The LTC3355 contains a nonsynchronous constant f
