The Texas Instruments UCC2808A-2 is a BiCMOS push-pull, high-speed, low-power pulse-width modulator designed for off-line or DC-to-DC fixed frequency current-mode switching power supplies. It integrates essential control and drive circuitry, minimizing external component count.
Key electrical features include operation up to 1 MHz, an on-chip error amplifier with a 2 MHz gain bandwidth product, and integrated gate drivers capable of 500mA peak source and 1A peak sink current. The device also incorporates an internal soft start and VDD clamping. It operates with a typical starting current of 130µA and a run current of 1mA, with undervoltage lockout (UVLO) thresholds at 4.3V/4.1V.
The UCC2808A-2 utilizes dual-output drive stages in a push-pull configuration. The dead time between outputs is typically 60ns to 200ns, limiting each output stage duty cycle to less than 50%. The device is available in TSSOP (PW) and SOIC (D) packages, both surface mountable.
This controller is suitable for applications requiring efficient power conversion with minimal external components. Its features make it a versatile choice for various power supply designs.
