The UCC28C43DGK from Texas Instruments is a BiCMOS low-power current-mode PWM controller. It is suitable for Boost, Flyback, and Forward converter topologies, offering a maximum duty cycle of 96% and operating frequencies up to 1MHz.
This controller features a wide operating voltage range of 7.6V to 18V and a maximum operating temperature of 105°C. Key electrical characteristics include fast, cycle-by-cycle overcurrent limiting with a 35ns response time, a peak driving current of ±1A, and a precise 2.5V error amplifier reference with ±1% accuracy.
Designed as an enhanced replacement for the UCx84x and UCx84xA families, the UCC28C43DGK offers pin-to-pin compatibility. It is available in an 8-VSSOP package, minimizing board space, and also in an 8-TSSOP, 8-MSOP package. The device features undervoltage lockout protections and a low operating current of 2.3mA at 52kHz.
This component is ideal for applications requiring efficient power management and precise control in a compact form factor. Its features make it suitable for industrial power supplies and other demanding electronic systems.
