Description: Dynamically-Adjustable / Synchronous Step-Down Controller with Integrated Voltage Positioning

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 an

Applications

* requiring a voltage-positioned supply. The voltage-positioning input (VPCS), combined with a high-DC-accuracy control loop, is used to implement a power supply that modifies its output set point in response to the load current. This arrangement decreases full-load power dissipation and reduces the r
