The UC2845AQD8R from Texas Instruments is a current-mode Pulse Width Modulation (PWM) controller optimized for off-line and DC-to-DC converter applications. This device operates at frequencies up to 500kHz and supports a maximum duty cycle of 48%. It is designed for switch mode power supplies (SMPS), DC-DC converters, power modules, industrial PSUs, and battery-operated PSUs.
The controller features extended temperature performance from -40°C to 125°C, low startup current (<0.5mA), and under-voltage lockout with hysteresis. It offers features such as automatic feed-forward compensation, pulse-by-pulse current limiting, enhanced load response characteristics, double pulse suppression, and a high current totem pole output. The UC2845AQD8R is available in an 8-SOIC package suitable for surface mounting.
Key electrical characteristics include an operating voltage range of 7.6V to 30V. The device supports multiple topologies including Boost, Buck, Flyback, and Forward configurations. Its control features include frequency control, making it a versatile component for various power supply designs.
