UC2842AD8 Description

Short technical summary and product information.

The UC2842AD8 from Texas Instruments is a current mode PWM controller suitable for various DC-DC converter topologies including Boost, Buck, Flyback, and Forward. It operates with a voltage range of 10V to 30V and supports frequencies up to 500kHz, with a maximum duty cycle of 96%.

 

This controller features essential control functions such as frequency control, undervoltage lockout with hysteresis, and double pulse suppression. It also includes pulse-by-pulse current limiting and automatic feedforward compensation for enhanced performance. The device is housed in a compact 8-SOIC surface mount package, making it suitable for space-constrained designs.

 

Key electrical characteristics include a low start-up current of less than 0.5mA and a high-current totem pole output. The UC2842AD8 is optimized for off-line and DC-DC converters, providing reliable power management solutions.
