MAX1762, MAX1791 High-Efficiency, 10-Pin ┬ÁMAX, Step-Down Controllers For Notebooks

The MAX1762 MAX1791 PWM Step-down controllers provide high efficiency, excellent transient response, and high DC output accuracy needed for stepping down, High-Voltage batteries to generate low-voltage CPU core, I/O, and chipset RAM supplies in notebook computers and PDAs.
Maxim's proprietary Quick-PWM" pulse-width Modulator is a free-running constant on-time type with input feed-forward. Its high operating frequency (300kHz) allows small external components to be utilized in PC board area-critical applications such as subnotebook computers and smart phones. PWM operation occurs at heavy loads, and Automatic switchover to pulse-skipping operation occurs at lighter loads. The external high-side p-channel and low-side N-Channel MOSFETs require no bootstrap components. The MAX1762 MAX1791 are simple, easy to compensate, and do not have the noise sensitivity of conventional fixed-frequency current-mode PWMs.
These devices achieve high efficiency at a reduced cost by eliminating the current-sense resistor found in traditional current-mode PWMs. Efficiency is further enhanced by their ability to drive synchronous-rectifier MOSFETs The MAX1762 MAX1791 come in a 10-pin MAX package and offer two fixed voltages (Dual Mode") for each device, 1.8V/2.5V/adj MAX1762 and 3.3V/5.0V/adj MAX1791 .
