ETA3499

3A, 1MHz Synchronous Buck Converter with 7.3V OVP

DESCRIPTION

FEATURES

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.
