MAX1557ETB+T - Brand New Maxim Integrated IC Chips
-
General Description
The MAX1556/MAX1556A/MAX1557 are low-operating current (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 pin selectable 1.8V, 2.5V, and 3.3V outputs; and is also adjustable. The MAX1557 delivers up to 600mA; has pin
selectable 1V, 1.3V, and 1.5V outputs; and is also adjustable.Features
