ETA3414S2F

The ETA3414 is a high-efficiency, DC-to-DC stepdown switching regulator, work in force PWM mode, 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 ETA3414 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 thermaloverload protection improves design reliability. ETA3414 is housed in a tiny SOT23-5 package. The ETA3414 high efficiency switching regulator is a small, simple, DC-to-DC step-down converter, work in force PWM mode, capable of delivering up to 1.5A of output current. The device operates in pulse-width modulation (PWM) at 3MHz from a 2.6V to 7.0V input voltage and provides an output voltage from 0.6V to VIN, making the ETA3414 ideal for on-board post-regulation applications. An internal synchronous rectifier improves efficiency and eliminates the typical Schottky free-wheeling diode. Using the on resistance of the internal high-side MOSFET to sense switching currents eliminates current-sense resistors, further improving efficiency and cost.
