Inputs for System Agent

http://onsemi.com

NCP5269A 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. NCP5269A 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. NCP5269A supports high

efficiency, fast transient response and provides power good signal.

ON Semiconductor proprietary adaptive-ripple control enables

seamless transition from CCM to DCM, where converter runs at

reduced switching frequency with much higher efficiency. The part

operates with input voltage ranging from 3.3 V to 28 V. NCP5269A is

available in a 20-pin 3 mm × 3 mm QFN package.
