MAX8720 Dynamically Adjustable 6-Bit VID Step-Down Controller

The MAX8720 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 the 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 6-bit digital-to-analog converter (DAC) over a 0.275V to 1.850V range in 25mV steps. The MAX8720 has independent four-level Logic inputs for setting the suspend voltage (S0-S1). Precision slew-rate control provides "just-in-time" arrival at the new DAC setting, minimizing surge currents to and from the battery. The internal DAC of the MAX8720 is synchronized to the slew-rate Clock for improved operation under aggressive Power Management of newer chipsets and operating systems that CAN make incomplete mode transitions. Remote feedback and ground-sense inputs allow easy compensation for IR drops in PC board traces. 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 MAX8720 is available in a 28-pin QSOP or 36-pin 6mm x 6mm thin QFN package.
