ETA3485 1.5A, 2MHz Step-Down Converter in SOT23-5 Package 

DESCRIPTION 

The ETA3485 is a high-efficiency, DC-to-DC step-down  switching regulator, capable of delivering up to 1.5A of  output current. The devices operate from an input  voltage range of 2.6V to 7V and provide output voltages  from 0.6V to VIN, making the ETA3485 ideal for low  voltage power conversions. Running at a fixed  frequency of 2MHz allows the use of small inductance  value and low DCR inductors, thereby achieving higher  efficiencies. Other external components, such as  ceramic input and output caps, can also be small due  to higher switching frequency, while maintaining  exceptional low noise output voltages. Built-in EMI  reduction circuitry makes this converter ideal power  supply for RF applications. Internal soft-start control  circuitry reduces inrush current. Short-circuit and  thermal-overload protection improves design reliability. ETA3485 is housed in a tiny SOT23-5L
