MAX1674EUA+T

High-Efficiency, Low-Supply-Current,  Compact, Step-Up DC-DC Converters

开关稳压器 Compact Step-Up DC/DC Converter

General Description

The MAX1674EUA+T MAX1674/MAX1675/MAX1676 compact, high-efficiency, step-up DC-DC converters fit in small μMAX packages. They feature a built-in synchronous rectifier, which improves efficiency and reduces size and cost by eliminating the need for an external Schottky diode. Quiescent supply current is only 16μA.

The input voltage ranges from 0.7V to VOUT, where  VOUT can be set from 2V to 5.5V. Start-up is guaranteed  from 1.1V inputs. The MAX1674/MAX1675/  MAX1676 have a preset, pin-selectable output for 5V or  3.3V. The outputs can also be adjusted to other voltages  using two external resistors.
