UCC2808DTR-1 Description

Short technical summary and product information.

The UCC2808DTR-1 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 requirements.

 

This controller features a push-pull topology with dual output drive stages. It operates at a frequency of 1MHz and supports a maximum duty cycle of 50%. The operating voltage range is 8.3V to 14V, with UVLO voltages specified at 12.5V/8.3V. Key electrical features include an on-chip error amplifier with a 2MHz gain bandwidth product, internal soft-start, and VDD clamping.

 

The UCC2808DTR-1 is housed in an 8-SOIC package suitable for surface mounting. The package measures 8-SOIC (0.154", 3.90mm Width). The operating temperature range is -55°C to 150°C (TJ). The output drive stages are capable of 500mA peak source current and 1A peak sink current.
