The Texas Instruments UCC38C42DR is a high-performance, current-mode Pulse Width Modulation (PWM) controller. It is an enhanced BiCMOS version offering pin-for-pin compatibility with industry-standard UCx84xA and UCx84x families, providing lower power consumption and improved efficiency.
This controller features an operating voltage range of 9V to 18V and supports frequencies up to 1MHz. Key electrical characteristics include a maximum duty cycle of 96%, a fast cycle-by-cycle overcurrent limiting response time of 35ns, and a peak driving current of ±1A. It also includes features like frequency control and an accurate 2.5V error amplifier reference.
The UCC38C42DR is suitable for various topologies including Boost, Flyback, and Forward converters. It is available in an 8-SOIC package, designed for surface mount applications, minimizing board space. The operating temperature range is 0°C to 70°C.
This device is an enhanced replacement for older UCx84x series controllers, offering improved performance with lower startup and operating currents. Its design facilitates efficient power conversion in a compact form factor.
