The UCC28086PWR from Texas Instruments is a BiCMOS pulse width modulation (PWM) controller for DC-to-DC or off-line fixed-frequency current-mode switching power supplies. It features dual output stages configured for push-pull topology, with outputs switching at half the oscillator frequency. The device supports programmable slope compensation and cycle-by-cycle current limiting.
Key electrical characteristics include an operating voltage range of 4.1V to 15V and a maximum duty cycle of 49%. The oscillator is programmable from 50 kHz to 1 MHz. It offers a low start-up current of 120 µA and a typical run current of 1.5 mA. The controller includes a high-current totem-pole dual output stage with 1-A sink and 0.5-A source capability, along with a current sense discharge transistor for improved dynamic response.
This controller is suitable for high-efficiency switch-mode power supplies, telecom DC-to-DC converters, point-of-load or point-of-use power modules, and low-cost push-pull and half-bridge applications. It operates within a temperature range of -40°C to 85°C.
The UCC28086PWR is available in an 8-TSSOP package, designed for surface mount applications. It features an internally trimmed bandgap reference and undervoltage lockout with hysteresis.
