The Texas Instruments UCC28083DR is a BiCMOS pulse width modulation (PWM) controller designed for offline fixed-frequency current-mode switching power supplies. It is configured for the push-pull topology, with dual output stages switching at half the oscillator frequency.
Key electrical specifications include an operating supply voltage range of 8.3V to 15V and a programmable switching frequency from 50kHz to 1MHz. The device features a 49% duty cycle and provides isolated output. For protection, it includes cycle-by-cycle current limiting.
This controller is housed in an 8-SOIC package and is designed for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. The UCC28083DR is suitable for high-efficiency switch-mode power supplies, telecom dc-to-dc converters, and point-of-load power modules.
