ETA3707/A

360nA Ultra-low Iq, COT Synchronous Buck Converter

DESCRIPTION

FEATURES

The ETA3707/A is a high-efficiency, DC-to-DC step-  Input Voltage Range: 2.1V to 5.5V

down switching regulator that features 360nA ultra-low  360nA Quiescent Current

quiescent current. ETA3707 can provide output

voltages from 1.2V to 3.3V, which is capable of

delivering up to 1A of output current. ETA3707A can

provide output voltages from 0.7V to 3.1V, which is

capable of delivering up to 500mA of output current.

ETA3707/A adopts an adaptive COT control scheme

that enables very fast transient response and provides

a very smooth transition when the output varies from
