MAX1674EUA+

The MAX1674EUA+ is a high-efficiency, low-supply-current compact step-up DC-DC Converter features 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 2 to 5.5V. Start-up is guaranteed from 1.1V inputs. The MAX1674 have a preset, pin-selectable output for 5 or 3.3V. The outputs can also be adjusted to other voltages using two external resistors.

• 94% Efficient at 200mA output current
• 16µA Quiescent supply current
• Internal synchronous rectifier (no external diode)
• 0.1µA Logic-controlled shutdown
• LBI/LBO low-battery detector
• Selectable current limit for reduced ripple
