ETA3425 1uA Ultra-Low Quiescent Current 0.6A Output Synchronous BUCK , DESCRIPTION FEATURES The ETA3425 is a high-efficiency, DC-to-DC step-down ? Ultra low 1uA Iq, and 1-2uA at standby switching regulator, capable of delivering up to 0.6A of ? Up to 96% Efficiency output current. It has an ultra-low quiescent current ? Up to 600mA Max Output Current below 1uA when there is no load. Running at a fixed ? 1.5MHz Frequency frequency of 1.5MHz allows the use of small inductance ? Light Load operation y value and low DCR inductors, thereby achieving higher ? Internal Compensation l l efficiencies. Other external components, such as ceramic ? Tiny Package a input and output caps, can also be small due to higher n i t switching frequency, while maintaining exceptional low O APPLICATIONS n noise output voltages. Internal soft-start control e e circuitry reduces inrush current. Short-circuit and ? Wearable thermal-overload protection improves design reliability. ? IOT s d i U ?
