MAX1672C/D规格书详情
General Description
The MAX1672 integrates a step-up DC-DC converter with a linear regulator to provide step-up/down voltage conversion. This device provides a constant output voltage for inputs that vary above and below the output voltage. It has a 1.8V to 11V input range and a preset 3.3V or 5V output. The output can also be set from 1.25V to 5.5V using two resistors. Typical efficiency is 85.
Features
♦ Step-Up/Down Voltage Conversion
♦ 1.8V to 11V Input Range
♦ 3.3V/5V or Adjustable Output Voltage Range
♦ Output Current:
300mA at 5V (VIN ≥ 2.5V)
150mA at 5V (VIN ≥ 1.8V)
♦ Smaller Inductor than SEPIC and Flybacks
♦ Load Disconnects from Input in Shutdown
♦ Supply Current from Battery:
85µA (No-Load)
0.1µA (Shutdown)
♦ PGI/PGO Low-Battery Comparator
♦ 16-Pin QSOP Package (Same Footprint as 8-pin SO)
♦ No External FETs Required
♦ Thermal and Short-Circuit Protection
Applications
Single-Cell, Lithium-Powered Portable Devices
2-Cell to 4-Cell AA Alkaline Hand-Held Equipment
3.3V and Other Low-Voltage Systems
Battery-Powered Devices with AC Input Adapters
Digital Cameras
