The Texas Instruments UCC38C43DR 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 UCx84x and UCx84xA families, providing lower power consumption and improved efficiency.
This controller supports multiple topologies including Boost, Flyback, and Forward converters. It features adjustable switching frequency up to 1MHz, a maximum duty cycle of 96%, and fast, cycle-by-cycle overcurrent limiting with a response time of 35ns. The operating voltage range is 7.6V to 18V, with a low startup current of 50μA and a low operating current of 2.3mA at 52kHz.
The UCC38C43DR is housed in an 8-SOIC package, suitable for surface mount applications. It includes features like frequency control, a transistor driver output, and a positive output configuration. The operating temperature range is 0°C to 70°C (TJ).
This device is an enhanced replacement for older UCx84x series controllers, offering improved performance and lower power consumption due to its BiCMOS technology. It is suitable for applications requiring efficient and reliable power management.
