Texas Instruments High-Performance Analog DC DC Switching Controllers UCC28086DR

The UCC28086DR 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 both outputs switching at half the oscillator frequency. The device includes programmable slope compensation, internal soft-start with a typical interval of less than 100 ¬µs, and cycle-by-cycle current limiting. It operates with a low start-up current of 120 ¬µA and a typical run current of 1.5 mA. The UCC28086DR supports a wide range of applications, including high-efficiency switch-mode power supplies, telecom DC-DC converters, and point-of-load power modules. It has an undervoltage lockout with hysteresis and is available in an 8-pin SOIC package. The device is rated for operation over a temperature range of -40¬8C to 85¬8C, making it suitable for various environmental conditions.
