NCP5269B is a synchronous buck controller that is optimized for converting the battery voltage or adaptor voltage into power supply rails required in notebook and desktop system. NCP5269B is designed for applications requiring dynamically selected slew−rate controlled output voltages. The soft−start is programmed by a single capacitor. Voltage identification logic−inputs select four resistor programmed set−point reference voltages that directly set the output voltage of the converter between 0.65 V to 1.5 V. NCP5269B supports high efficiency, fast transient response and provides power good signal. Forced CCM operation provides DDR termination voltage with source/sink capability. The part operates with input voltage ranging from 3.3 V to 28 V. NCP5269B is available in a 20−pin 3 mm x 3 mm QFN package.
