Overview

UNISONIC TECHNOLOGIES CO.
, LTD SR2803 330KHZ, 3A SYNCHRONOUS BUCK CONTROLLER DESCRIPTION LINEAR INTEGRATED CIRCUIT The UTC SR2803 is a synchronous buck regulator.
The device provides 3A of continuous load current over a wide input voltage of 4V~28V.
Current mode control provides fast transient response and cycle by cycle current limit.
Integrates soft start, and shutdown mode.
The UTC SR2803 can provide low-ripple power, high efficiency, and perfect transient characteristics.
The duty ratio varies linearly from 0% to 92% in the PWM control.
The error amplifier circuit and soft-start circuit included in this device can prevent overshoot at startup.
An enable function, an over current prot...
