Synchronous Buck
Controller with Auto Power
Saving Mode and 2-Bit VID
Inputs for System Agent
NCP81039 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. NCP81039 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. NCP81039 supports high efficiency, fast transient response and...
