Adjustable, VID-compliant, step-down controller for notebook CPUs

( 01 Dec 2004 )

Maxim Integrated Products' MAX8720 step-down controller features dynamically adjustable output, ultra-fast transient response, high dc accuracy, and the high efficiency required for CPU-core power supplies. The company's Quick-PWM, 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 constant switching frequency.



The MAX8720 features fast transient response.

The MAX8720's output voltage is dynamically adjusted through the 6-bit DAC over a 0.275 to 1.850V range in 25mV steps. Independent, four-level logic inputs set the suspend voltage (S0-S1). The device is available in a 28-pin QSOP or 36-pin TQFN package, and extended temperature range is -40 to +85°C
