UCC28C44D

The Texas Instruments UCC28C44D is a versatile offline controller designed for power management applications. It integrates Pulse Width Modulation (PWM) and Under-Voltage Lockout (UVLO) features, housed in a standard 8-SOIC package for surface mount applications.

This controller supports a wide input voltage range of 9V to 18V, making it suitable for various power supply designs. It offers a high switching frequency capability of up to 1MHz, allowing for efficient power conversion and smaller component sizes. The maximum duty cycle is rated at 48%, providing flexibility in power output control. The device is configured for positive output and utilizes a transistor driver output type.

Designed for boost, flyback, and forward converter topologies, the UCC28C44D does not incorporate a synchronous rectifier. Its operating temperature range is from -40°C to 105°C (TJ), ensuring reliable performance in diverse environmental conditions. The surface mountable 8-SOIC package (0.154", 3.90mm Width) is standard for many electronic assemblies.

Key specifications include a single output phase and a single output configuration. The control features focus on frequency control, with no clock synchronization required. This component is ideal for designers seeking a robust and efficient offline controller for step-up and step-up/step-down power supply applications.
