The UCC3813-5 is a low-power, economy BiCMOS current mode PWM controller designed for use in switch mode power supplies (SMPS) and DC-DC converters. It features a typical starting supply current of 100µA and an operating supply current of 500µA, allowing for efficient power management. The device operates at frequencies up to 1MHz and includes internal soft start and fault soft start capabilities, which help to minimize inrush current during startup. This PWM controller offers a 1A totem-pole output with a typical response time of 70ns from the current-sense input to the gate-drive output. It has a voltage reference tolerance of 1.5%, ensuring stable operation across various conditions. The UCC3813-5 is particularly suitable for battery-operated power supply systems due to its lower reference voltage of 4V, making it an ideal choice for applications requiring efficient power conversion in compact designs. The device is available in an 8-pin TSSOP package and is specified for operation within a temperature range of 0°C to 70°C.
