UCC2808APWTR-2 Description

Short technical summary and product information.

The Texas Instruments UCC2808APWTR-2 is a BiCMOS push-pull, high-speed, low-power pulse-width modulator. It integrates control and drive circuitry for off-line or DC-to-DC fixed frequency current-mode switching power supplies, minimizing external component count.

 

This controller operates at frequencies up to 1 MHz and features an on-chip error amplifier with a 2MHz gain bandwidth product. It includes integrated gate drivers and a soft-start function. The device supports a voltage range of 4.1V to 15V and has a maximum duty cycle of 49%. The output drive stages can provide 500mA peak source current and 1A peak sink current.

 

Packaged in an 8-TSSOP, the UCC2808APWTR-2 is designed for surface mount applications. Its operating temperature range is -40°C to 85°C (TA). The device offers features like frequency control and is suitable for various power supply designs requiring a push-pull topology.

 

Key electrical characteristics include a typical starting current of 130µA and a typical run current of 1mA. The device has 2 outputs and 1 output phase, with a positive output configuration.
