1A, 1.5MHz, Synchronous

Step Down DC/DC Converter

EC3201S

General Description

EC3201S is a high efficiency step down DC/DC converter operated with current mode and constant frequency.

The internal switch and synchronous rectifier are integrated for high efficiency. External Schottky diodes are not

required. The supply current is only 110µA during operation and drops to less than 1µA in shutdown. EC3201S

can supply 1A of load current from 2.5V to 5.5V supply voltage.

The switching frequency is set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. It

can run 100% duty cycle for low dropout application. The output voltage of EC3201S is adjustable from the FB

pin. EC3201S is RoHS compliant and Lead (Pb) Free.
