19-2527; Rev 0; 7/02 Low-Output-Voltage, 800mA, PWM Step-Down DC-DC Converters General Description The MAX1927/MAX1928 800mA step-down converters power low-voltage microprocessors in pact equipment requiring the highest possible efficiency. The MAX1927/MAX1928 are optimized for generating low output voltages (down to 750mV) at high efficiency using small external ponents. The supply voltage range is from 2.6V to 5.5V and the guaranteed minimum output current is 800mA. 1MHz pulse-width modulation (PWM) switching allows for small external ponents. A unique control scheme minimizes ripple at light loads, while maintaining a low 140µA quiescent current. The MAX1927/MAX1928 include a...
