MAX1556/MAX1556A/MAX1557 19-3336; Rev 3; 1/11 EVAALVUAAILTAIOBNLEKIT 16µA IQ, 1.2A PWM Step-Down DC-DC Converters General Description The MAX1556/MAX1556A/MAX1557 are low-operatingcurrent (16µA), fixed-frequency step-down regulators. High efficiency, low-quiescent operating current, low dropout, and minimal (27µA) quiescent current in dropout make these converters ideal for powering portable devices from 1-cell Li-ion or 3-cell alkaline/NiMH batteries. The MAX1556 delivers up to 1.2A; has pinselectable 1.8V, 2.5V, and 3.3V outputs; and is also adjustable. The MAX1557 delivers up to 600mA; has pinselectable 1V, 1.3V, and 1.5V outputs; and is also adjustable. The MAX1556/MAX1556A/MAX1557...
