The UCC38084DRG4 from Texas Instruments is a BiCMOS pulse width modulation (PWM) controller designed for fixed-frequency current-mode switching power supplies. This device is suitable for DC-to-DC and off-line applications, utilizing a push-pull topology with dual output stages.
Key electrical specifications include an operating voltage range of 4.1V to 15V and a maximum duty cycle of 49%. The controller operates at a frequency of 200kHz and offers features such as current limiting and frequency control. It supports multiple topologies including Buck, Boost, Half-Bridge, and Push-Pull configurations.
This controller integrates several features to enhance performance and simplify design. It includes programmable slope compensation, cycle-by-cycle current limiting, and an internal soft-start interval of 3.5 ms. The device also boasts low start-up current (120 µA) and typical run current (1.5 mA), along with a single external component oscillator programmable from 50 kHz to 1 MHz.
The UCC38084DRG4 is housed in an 8-SOIC package and is designed for surface mount applications. It operates within a temperature range of 0°C to 70°C (TA). The device also features a high-current totem-pole dual output stage, a current sense discharge transistor for improved dynamic response, an internally trimmed bandgap reference, and undervoltage lockout with hysteresis.
