The UCC28086PW is a BiCMOS pulse width modulation (PWM) controller designed for DC-DC or off-line fixed-frequency current-mode switching power supplies. It features a dual output stage configured for push-pull topology, with outputs switching at half the oscillator frequency. The device includes programmable slope compensation, cycle-by-cycle current limiting, and an internal discharge transistor to enhance dynamic response. The UCC28086PW has a low start-up current of 120 ¬µA and a typical run current of 1.5 mA. It operates with a soft-start interval of less than 100 ¬µs, making it suitable for applications where rapid power-up is required. The device supports a wide range of applications, including high-efficiency switch-mode power supplies, telecom DC-DC converters, and point-of-load power modules. It is available in an 8-pin TSSOP package and has an operating temperature range of -40¬8C to 85¬8C. The UCC28086PW also features undervoltage lockout with hysteresis, ensuring reliable operation under varying conditions.
