The UCC2808AQDR-2Q1 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 off-line 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, with outputs switching at half the oscillator frequency. It supports operation up to 1 MHz and includes features like internal soft start, an on-chip error amplifier with a 2 MHz gain bandwidth product, and VDD clamping. The output drive stages can deliver 500 mA peak-source current and 1 A peak-sink current.
The UCC2808AQDR-2Q1 is housed in an 8-SOIC package and is designed for surface mount applications. It operates within a temperature range of -40°C to 125°C (TJ). Key electrical specifications include a typical starting current of 130 μA and a typical run current of 1 mA. The maximum duty cycle is limited to 49% to ensure proper operation of the push-pull configuration.
Qualified for automotive applications, this controller also offers ESD protection exceeding 1500 V per MIL-STD-883 and 200 V using the machine model. Its current sense discharge transistor enhances dynamic response.
