Texas Instruments High-Performance Analog PMIC - PMIC - Voltage Regulators - DCDC Switching Controllers - UCC38084PWR UCC38084PWR

The UCC38084PWR 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, and cycle-by-cycle current limiting, making it suitable for high-efficiency switch-mode power supplies and telecom DC-DC converters. The UCC38084 operates with a supply voltage range of 4.1 V to 15 V and has a low start-up current of 120 ¬µA. It supports a switching frequency that can be programmed from 50 kHz to 1 MHz, with a typical frequency of 200 kHz. The device is available in an 8-pin TSSOP package and is rated for an operating temperature range of 0¬8C to 70¬8C. The UCC38084 also features undervoltage lockout with hysteresis and a high-current totem-pole output stage capable of driving a 1-A sink and 0.5-A source. Engineers considering this product should note its suitability for applications requiring efficient power management and its ability to handle various topologies, including buck, boost, and half-bridge configurations.
