MAX8743 Overview
Key Specifications
Package: QSOP
Mount Type: Surface Mount
Pins: 28
Max Frequency: 540 kHz
Description
The MAX8743 is a dual pulse-width modulation (PWM) controller configured for step-down (buck) topologies that provides the high efficiency, excellent transient response, and high DC output accuracy necessary for stepping down high-voltage batteries to generate lowvoltage chipset and RAM power supplies in notebook computers. The CS_ inputs can be used with low-side sense resistors to provide accurate current limits or can be connected to LX_, using low-side MOSFETs as current-sense elements.
Key Features
- Ultra-High Efficiency
- Accurate Current-Limit Option
- Quick-PWM™ with 100ns Load-Step Response
- 1% VOUT Accuracy over Line and Load
- High Output Impedance in Shutdown
