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  Energy Harvest f ETA3425 is housed in a tiny SOT23-5 and DFN2x2-6  Battery powered devices n package 图 o C TYPICAL APPLICATION 晶 n o 芯 i r
