The Texas Instruments UCC3802 is a high-speed, low-power integrated circuit designed for fixed frequency current-mode switching mode power supplies. It operates at up to 1MHz with a maximum duty cycle of 100% and features a typical starting supply current of 100µA and operating current of 500µA.
Key electrical characteristics include adjustable switching frequency, current limiting, dead time control, an error amplifier, leading-edge blanking, and internal soft start. The device provides a 1A totem-pole output with a typical response time of 70ns from current-sense to gate drive output. It also features a 1.5% tolerance voltage reference.
Available in SOIC and TSSOP packages, the UCC3802 operates within a temperature range of 0°C to 70°C. Its design incorporates features like internal full-cycle soft start and internal leading-edge blanking of the current-sense input, offering a minimal parts count solution for power supply designs.
This controller is suitable for various power supply topologies including Boost and Flyback configurations. Its low power consumption and high frequency operation make it a versatile component for applications requiring efficient power management.
