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-sta
