AEC-Q100

The Microchip constant on-time, dual phase, synchronous buck controller featuring a unique adaptive on-time control architecture with HyperLight Load® and phase shedding features enabled. It operates over an input supply range from 4.5V to 36V and can be used to supply up to 50A of output current. The output voltage is adjustable down to 0.6V with an ensured accuracy of ±1%.

0.6V internal reference with ±1% accuracy

Novel ripple injection method to allow greater than 50% duty cycle operation

Secondary LDO to improve system efficiency

Droop feature to support adaptive voltage positioning (AVP) for improved load transient response
