1MHz Synchronous Buck Converter - ETA
Description
ETA3499
3A, 1MHz Synchronous Buck Converter with 7.
3V OVP
DESCRIPTION
The ETA3499 is a high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 3A of output current.
The devices operate from an input voltage range of 2.
4V to 7.
3V and provide output voltages from 0.
6V to VIN, making the ETA3499 ideal for low voltage power conversions.
Running at a fixed frequency of 1MHz 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.
Internal soft-start control circuitry reduces inrush current.
Short-circuit and thermal-overload protection improves design reliability.
ETA3499 is housed in a tiny SOT23-6L package
