The UC2844AQD8R from Texas Instruments is a current mode Pulse Width Modulation (PWM) controller IC. It is an improved version of the UC284x family, offering features optimized for offline and DC-to-DC converters.
Key electrical specifications include an operating voltage range of 10V to 30V and a maximum switching frequency of up to 500kHz. The device supports various topologies such as Boost, Buck, Flyback, and Forward converters. It has a maximum duty cycle of 48% and features frequency control.
Designed for robust performance, the UC2844AQD8R operates across an extended temperature range of -40°C to 125°C. It includes features like low startup current (<0.5mA), pulse-by-pulse current limiting, and under-voltage lockout with hysteresis. The controller is housed in an 8-SOIC package suitable for surface mounting.
This controller is well-suited for applications including switch mode power supplies (SMPS), DC-DC converters, power modules, industrial power supplies, and battery-operated power supplies.
