Dynamically-Adjustable, Synchronous Step-Down Controller with Integrated
Voltage Positioning
General Description
The MAX1813 step-down controller is intended for core CPU DC-DC converters in notebook computers.
The controller features a dynamically adjustable output (5bit DAC), ultra-fast transient response, high DC accuracy, and high efficiency necessary for leading-edge CPU core power supplies.
Maxim’s proprietary QuickPWM™ quick-response, constant-on-time PWM control scheme handles wide input/output
voltage ratios with ease and provides 100ns “instant-on” response to load transients while maintaining a relatively constant switching frequency.
The MAX1813 is designed ...
