The UCC38084DR from Texas Instruments is a BiCMOS pulse width modulation (PWM) controller suitable for fixed-frequency current-mode switching power supplies. This device is configured for the push-pull topology, with dual output stages switching at half the oscillator frequency. It supports a wide input voltage range from 4.1V to 15V and operates at a frequency of 200kHz with a maximum duty cycle of 49%.
Key features include programmable slope compensation, cycle-by-cycle current limiting, and an internal soft-start function. The controller also boasts low start-up current (120 µA) and typical run current, along with a single external component oscillator programmable from 50 kHz to 1 MHz. The high-current totem-pole dual output stage can drive a push-pull configuration with 1-A sink and 0.5-A source capability. An integrated current sense discharge transistor improves dynamic response, and the device includes an internally trimmed bandgap reference and undervoltage lockout with hysteresis.
Designed for high-efficiency switch-mode power supplies, telecom DC-to-DC converters, point-of-load or point-of-use power modules, and low-cost push-pull and half-bridge applications, the UCC38084DR is available in an 8-SOIC package suitable for surface mounting.
