The UCC28C45D from Texas Instruments is a versatile current-mode Pulse Width Modulation (PWM) controller. It is suitable for multiple DC/DC converter topologies including Boost, Flyback, and Forward converters. This device operates within a voltage range of 7.6V to 18V and supports adjustable switching frequencies up to 1MHz.
Key electrical features include a maximum duty cycle of 48%, a fast cycle-by-cycle overcurrent limiting response time of 35ns, and a peak driving current of ±1A. It also incorporates an accurate 2.5V error amplifier reference with ±1% accuracy. The controller offers features like frequency control and undervoltage lockout protections.
Packaged in an 8-SOIC surface mount package, the UCC28C45D is designed for industrial applications. It operates across a temperature range of -40°C to 105°C (TJ). Its low operating current and startup current make it suitable for power-sensitive designs.
