ETA3424

The ETA3424 is a high-efficiency, DC-to-DC step-down switching regulator, work in forced PWM mode, capable of delivering up to 1.5A of output current. The devices operate with an input voltage range from 2.6V to 7V and provide fixed output voltages of 1.2V, 2.5V and 3.3V, making the ETA3424 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.
