The UCC2813D-4 is a synchronous pulsewidth modulation (PWM) controller from Texas Instruments that is designed for controlling motor and load power in electronic systems. It can achieve efficiencies up to 95% and is suitable for driving a MOSFET or IGBT with up to 3.5 A output current. The device features open loop voltage mode PWM control, with built-in bootstrap drive for high side power FETs, along with over current, over temperature, and under voltage protection. The UCC2813D-4 also includes short circuit protection, undervoltage lockout (UVLO) with hysteresis, and a frequency fold-back feature. It operates from a 4.5 V to 14 V supply voltage and can provide an output voltage of up to 2.5 V. The UCC2813D-4 has a wide operating temperature range of -40°C to +95°C and is available in 8-pin SOIC, 8-pin SOI, and 8-pin SOE packages.
