General Description

The EC3207 is a high-efficiency, DC-to-DC Step-down switching regulators, capable of delivering up to 1.4A of output current.

The device operates from an input voltage range of 2.5V to 6.0V and provides an output voltage from 0.6V to VIN, making the EC3207 ideal for low voltage power conversions.

Running at a fixed frequency of 1.5MHz allows the use of small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples.

This low noise output along with its excellent efficiency achieved by the internal synchronous rectifier, making EC3207 an ideal green replacement for large power consuming linear regulators.

Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal overload protection improves design reliability.
