MAX1541ETL MAX1541 Dual Step-Down Controllers with SaturationProtection, Dynamic Output, and Linear Regulator
Product DescriptionProduct DescriptionThe MAX1540/MAX1541 dual pulse-width modulation(PWM) controllers provide the high efficiency, excellenttransient response, and high DC-output accuracy nec-essary for stepping down high-voltage batteries to gen-erate low-voltage chipset and RAM power supplies innotebook computers.The Maxim proprietary Quick-PWMTM controllers arefree running, constant on-time with input feed forward.This configuration provides ultra-fast transientresponse, wide input-output (I/O) differential range, lowsupply current, and tight load-regulation characteris-tics. The controllers can accurately sense the inductorcurrent across an external current-sense resistor inseries with the output to ensure reliable overload andinductor saturation protection. Alternatively, the con-trollers can use the synchronous rectifier itself or loss-less inductor current-sensing methods to provideoverload 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 theMAX1992/MAX1993 data sheet.
