UC2842AN Description

Short technical summary and product information.

The UC2842AN from Texas Instruments is a versatile current-mode Pulse Width Modulation (PWM) controller. It is designed to support a wide range of DC-DC converter topologies including boost, buck, flyback, and forward configurations.

 

This controller operates with an input voltage range of 10V to 30V and can achieve switching frequencies up to 500kHz. It offers a maximum duty cycle of 96% and features frequency control for precise operation. The output type is a transistor driver, suitable for positive or isolation-capable outputs.

 

Packaged in an 8-pin PDIP (Plastic Dual In-line Package), the UC2842AN is designed for through-hole mounting. Its operating temperature range is -40°C to 85°C (TA), making it suitable for various environmental conditions. The device also includes features like a quiescent current of 12mA and an input current of 11mA.
