MAX1716, MAX1854, MAX1855 High-Speed, Adjustable, Synchronous Step-Down Controllers With Integrated Voltage Positioning

The MAX1716 MAX1854 MAX1855 Step-down controllers are intended for core CPU DC-DC Converters in notebook computers. They feature a dynamically adjustable output (5-bit DAC), 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 MAX1716 MAX1854 MAX1855 are designed specifically for CPU core applications requiring a voltage-positioned supply. The voltage-positioning input (VPS), 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 required number of output capacitors.
The 28V input range of the MAX1716 MAX1854 MAX1855 enables single-stage buck conversion from High-Voltage batteries for the maximum possible efficiency. Alternatively, the devices' high-frequency capability combined with two-stage conversion (stepping down the +5V system supply instead of the battery) allows the smallest possible physical size. The output voltage CAN be dynamically adjusted through the 5-bit digital-to-analog converter (DAC) inputs.
The MAX1716 MAX1854 MAX1855 are available in a 24-pin QSOP package. For applications requiring SpeedStep power control (see the MAX1717 .
