MAX1540A, MAX1541 Dual Step-Down Controllers With Saturation Protection, Dynamic Output, And Linear Regulator

The MAX1540A MAX1541 dual pulse-width modulation (PWM) controllers provide the high efficiency, excellent transient response, and high DC-output accuracy necessary for stepping down High-Voltage batteries to generate low-voltage chipset and RAM power supplies in notebook computers.
The Maxim proprietary Quick-PWM" controllers are free running, constant on-time with input feed forward. This configuration provides ultra-fast transient response, wide input-output (I/O) differential range, low supply current, and tight load-regulation characteristics. The controllers CAN accurately sense the inductor current across an external current-sense resistor in series with the output to ensure reliable overload and inductor saturation protection. Alternatively, the controllers CAN use the synchronous Rectifier itself or lossless inductor current-sensing methods to provide overload protection with lower power dissipation.
For a single Step-down PWM Controller with inductor-saturation protection, external-reference input voltage, and dynamically selectable output voltages, refer to the MAX1992 MAX1993 data sheet.
