The UCC3808DTR-2 from Texas Instruments is a BiCMOS push-pull pulse-width modulator. It is designed for high-speed, low-power applications, providing the necessary control and drive circuitry for fixed-frequency current-mode switching power supplies with minimal external components.
Key electrical specifications include an operating voltage range of 4.1V to 15V and a maximum duty cycle of 49%. The device operates at a frequency of 194kHz and features frequency control. It has a typical starting current of 130μA and a typical run current of 1mA. The output drive stages are capable of 500mA peak source current and 1A peak sink current.
This controller is housed in an 8-SOIC package and is designed for surface mount applications. The operating temperature range is 0°C to 70°C (TA). The UCC3808DTR-2 is suitable for various power supply designs requiring a push-pull topology.
Features include an on-chip error amplifier with a 2MHz gain bandwidth product and an internal soft-start function. The dual output drive stages operate in a push-pull configuration, switching at half the oscillator frequency. The dead time between outputs is typically 60ns to 200ns, limiting each output stage duty cycle to less than 50%.
