UCC28C43DR TI DC-DC Controllers
The UCC28C43DR is a BiCMOS low-power current-mode PWM controller from Texas Instruments in SOIC-8 package. It operates from 7.6 V to 18 V, with switching frequency up to 1 MHz and 1-A totem-pole output for driving MOSFETs. Features include undervoltage lockout (8.5-V turn-on, 7.6-V turn-off), low start-up current (<0.5 mA), cycle-by-cycle current limiting, and automatic feed-forward compensation. Ideal for DC-DC converters (flyback, forward, boost), off-line power supplies, battery chargers, and LED drivers requiring high-frequency operation and low power consumption.
