Features

AI Translation
  • The MAX1717 step-down controller is intended for core CPU DC-DC converters in notebook computers. It features a dynamically adjustable output, ultra-fast transient response, high DC accuracy, and high efficiency needed for leading-edge CPU core power supplies.
  • Maxim’s proprietary Quick-PWM™ 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 output voltage can be dynamically adjusted through the 5-bit digital-to-analog converter (DAC) inputs over a 0.925V to 2V range.
  • A unique feature of the MAX1717 is an internal multiplexer (mux) that accepts two 5-bit DAC settings with only five digital input pins.
  • Output voltage transitions are accomplished with a proprietary precision slew-rate control that minimizes surge currents to and from the battery while guaranteeing “just-in-time” arrival at the new DAC setting.
  • High DC precision is enhanced by a two-wire remotesensing scheme that compensates for voltage drops in the ground bus and output voltage rail.
  • Alternatively, the remote-sensing inputs can be used together with the MAX1717’s high DC accuracy to implement a voltage-positioned circuit that modifies the load-transient response to reduce output capacitor requirements and full-load power dissipation.
  • Single-stage buck conversion allows these devices to directly step down high-voltage batteries for the highest possible efficiency.
  • Alternatively, two-stage conversion (stepping down the +5V system supply instead of the battery) at a higher switching frequency allows the minimum possible physical size.
  • The MAX1717 is available in a 24-pin QSOP package.
  • Quick-PWM Architecture
  • ±1% VOUT Accuracy Over Line and Load
  • 5-Bit On-Board DAC with Input Mux
  • Precision-Adjustable VOUT Slew Control
