UCC28C42DR TI DC DC Switching Controllers
The UCC28C42 is a high-speed, current-mode PWM controller designed for industrial power supplies. It operates from 9V to 18V (start-up threshold of 9V, UVLO hysteresis 14.5V on / 9V off). The device features a 1MHz capable oscillator and a 1A peak output current. It offers low start-up current (0.5 mA) and fast cycle-by-cycle current limiting. Selection is ideal for high-frequency, high-density isolated designs. Applications include off-line flyback converters for 48V telecom, isolated DC-DC converters for industrial automation, and battery charging circuits requiring robust current-mode control.
