UCC2808D-2 Description

Short technical summary and product information.

The UCC2808D-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 requirements.

 

This controller operates with a voltage range of 4.1V to 15V and a frequency of 194kHz, featuring a maximum duty cycle of 49%. It includes an on-chip error amplifier with a 2MHz gain bandwidth product and an internal soft-start function. The output drive stages are capable of 500mA peak source current and 1A peak sink current.

 

The UCC2808D-2 is housed in an 8-SOIC package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C (TA). The device is RoHS3 compliant and has an MSL 1 rating, indicating unlimited shelf life under standard conditions.
