ADP2311 - Synchronous Step-Down Regulator

Datasheet Summary

The ADP2311 is a fully integrated, dual output, synchronous step-down dc-to-dc regulator.

The regulator operates from input voltages of 4.5 V to 18 V, and the output can regulate down to 0.6 V.

Each channel can provide up to 1 A of continuous output current.

Input voltage: 4.5 V to 18 V ±1.0% output accuracy Integrated MOSFET: 110 mΩ/60 mΩ typical Continuous output current: 1 A/1 A Power fail comparator generates warning Power-on reset with programmable delay timer Adjustable voltage monitor for power-down (Channel 2) Watchdog refresh input Dual phase with 180° out-of-phase operation Fixed switching frequency: 300 kHz Internal compensation and soft start Stable with low ESR output ceramic capacitors Precision enable input Power feedback during power.
