2808A-1

Product Overview

2808A-1 is commonly associated with Texas Instruments UCC2808A-1 series low-power current-mode push-pull PWM controllers, where 2808A-1 is often used as the device marking for SOIC package versions such as UCC2808AD-1 and UCC2808ADTR-1. The device contains the control and drive circuitry required for fixed-frequency current-mode switching power supplies, especially push-pull, half-bridge and isolated DC-DC converter designs. With low startup current, programmable oscillator, dual alternating outputs, current-sense input, undervoltage lockout and compact 8-pin SOIC / TSSOP package options depending on the full ordering code, it is suitable for telecom power modules, isolated converters, industrial power supplies, battery-powered systems and legacy SMPS repair applications.
