UC2846DWTR Description

Short technical summary and product information.

The UC2846DWTR from Texas Instruments is a dual-ended, 500kHz current mode PWM controller. It is designed to implement fixed-frequency, current-mode control schemes with a minimal external component count.

 

Key electrical specifications include a wide input voltage range of 6.95V to 40V and a maximum duty cycle of 50%. The controller supports various topologies such as Boost, Flyback, Forward, Full-Bridge, Half-Bridge, and Push-Pull. It features programmable pulse-by-pulse current limiting, automatic feedforward compensation, and a ±1% band gap reference.

 

This device is available in a 16-SOIC package suitable for surface mounting. It operates within an ambient temperature range of -40°C to 85°C. The UC2846DWTR is noted as not recommended for new designs, but remains available for existing customers.
