The UCC3808D-2 from Texas Instruments is a BiCMOS push-pull pulse-width modulator designed for high-speed, low-power applications. It integrates essential control and drive circuitry for offline or DC-to-DC fixed-frequency current-mode switching power supplies, minimizing external component count.
This controller features dual output drive stages in a push-pull configuration, operating at half the oscillator frequency. It supports a voltage range of 4.1V to 15V and has a maximum duty cycle of 49%. The device operates at a frequency of 194kHz and includes features such as an on-chip error amplifier with a 2MHz gain bandwidth product and an internal soft-start function.
The UCC3808D-2 is housed in an 8-SOIC package, suitable for surface mount applications. Its operating temperature range is 0°C to 70°C. The device is designed for applications requiring efficient power conversion with a push-pull topology.
