Description

The MAX1626ESA /MAX1627 step-down DC-DC switching controllers provide high efficiency over loads ranging from 1mA to more than 2A. A unique current-limited,pulse-frequency-modulated (PFM) control scheme operates with up to a 100% duty cycle, resulting in very low dropout voltages. This control scheme eliminates minimum load requirements and reduces the supply current under light loads to 90μA (versus 2mA to 10mA for common pulse-width modulation controllers). MAX1626ESA Features • Low Dropout Voltage• 100% Maximum Duty Cycle• Soft-Start Limits Start-Up Current• Efficiency >90% (3mA to 2A Loads)• Output Power >12.5W• 90μA Max Quiescent Current• 1μA Max Shutdown Current• Up to 300kHz Switching Frequency• 16.5V Max Input Voltage• Output Voltage: 5V/3.3V (MAX1626) Adjustable (MAX1627)• Current-Limited Control Scheme MAX1626ESA Applications • PCMCIA Power Supplies• Personal Digital Assistants• Hand-Held Computers• Portable Terminals• Low-Cost Notebook Computer Supplies• 5V to 3.3V Green PC Applications• High-Efficiency Step-Down Regulation• Minimum-Component DC-DC Converters• Battery-Powered Applications
