The UCC38084PWRG4 is a BiCMOS pulse width modulation (PWM) controller designed for DC-DC or off-line fixed-frequency current-mode switching power supplies. It features a dual output stage configured for push-pull topology, with outputs switching at half the oscillator frequency. The device includes programmable slope compensation, internal soft-start with a typical interval of 3.5 ms, and cycle-by-cycle current limiting. It operates with a low start-up current of 120 µA and a typical run current of 1.5 mA. The UCC38084 supports a supply voltage range of 4.1 V to 15 V and is suitable for applications such as high-efficiency switch-mode power supplies, telecom DC-DC converters, and point-of-load power modules. The device is available in an 8-pin TSSOP package and has a maximum duty cycle of 49%. It also incorporates undervoltage lockout with hysteresis, ensuring reliable operation. The UCC38084 is compliant with halogen-free standards and is expected to remain available until at least 2028.
