The Texas Instruments UCC2813D-0 is an economy, low-power, BiCMOS current-mode Pulse Width Modulation (PWM) controller designed for off-line and DC-to-DC fixed-frequency switching power supplies. It operates at up to 1MHz with a typical starting supply current of 100µA and an operating supply current of 500µA.
Key electrical specifications include a maximum duty cycle of 99% and an operating supply voltage range of 6.9V to 12V. The device features adjustable switching frequency, current limiting, dead time control, an error amplifier, and internal soft start. It also includes internal leading-edge blanking of the current-sense signal and a 1A totem-pole output.
This controller supports multiple topologies including Boost, Flyback, and Forward converters. It is housed in an 8-SOIC package with surface mount mounting type. The operating temperature range is -40°C to 85°C (TA).
The UCC2813D-0 is pin-compatible with the UCC3802, UC3842, and UC3842A device families, offering a low parts count solution for power supply designs.
