上海钰泰 ETA3417S2F SOT23-5L 3MHz降压转换器

DESCRIPTION
The ETA3417 is a high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 2.5A 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 ETA3417 ideal for low voltage power conversions. Running at a fixed frequency of 3MHz 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.
ETA3417 is housed in a tiny SOT23-5L
