3A, 1MHz, Low-Voltage, Step-Down Regulators with Synchronous Rectification and Internal Switches
General Description
The MAX1830/MAX1831 constant-off-time, pulse-widthmodulated (PWM) step-down DC-DC converters are ideal for use in 5V and 3.3V to low-voltage conversion necessary in notebook and subnotebook puters. These devices feature internal synchronous rectification for high efficiency and reduced ponent count. They require no external Schottky diode. The internal 45mΩ PMOS power switch and 55mΩ NMOS synchronous-rectifier switch easily deliver continuous load currents up to 3A. The MAX1830 produces preset +2.5V,...
