General Description

ECL2401 series is a group of highefficiency synchronous-rectification type buck regulator using a constant requency, current mode architecture.
Automatic PWM/PFM mode operation increasesefficiency and decreases output voltage ripple at light loads, further extending battery life. Switching frequency is internally set at 1.4MHz, allowing the use of small surface mount inductors and capacitors. 100% duty cycle provides low dropout operation.

Features

◆Output Current : 800mA
