The MAX1540/MAX1541 is a dual pulse width modulation (PWM) controller that offers high efficiency, excellent response to changing loads, and high-precision DC output, essential for reducing high voltage from batteries to low-voltage supplies for chipsets and RAM in laptops.
Maxim's proprietary Quick-PWM controllers operate with free-running, fixed-on-time, and input supply. This configuration provides extremely fast response to transients, wide input-output differential, low power consumption, and tight load regulation.
Controllers can precisely detect the inductor current via an external current sense resistor, providing reliable overload and saturation protection. Alternatively, they can use a synchronous rectifier controller or a lossless mechanism.
