SNVS033D – MAY 2004 – REVISED NOVEMBER 2015 LM2621 Low Input Voltage, Step-Up DC-DC Converter
1 Features 3 Description The LM2621 is a high efficiency, step-up DC-DC
switching regulator for battery-powered and low input
voltage systems. It accepts an input voltage between
1.2 V and 14 V and converts it into a regulated output
voltage. The output voltage can be adjusted between
1.24 V and 14 V. It has an internal 0.17-О© N-Channel
MOSFET power switch. Efficiencies up to 90% are
achievable using the LM2621. 1 Small VSSOP8 Package (Half the Footprint of
Standard 8-Pin SOIC Package)
1.09-mm Package Height
Up to 2-MHz Switching Frequency
1.2-V to 14-V Input Voltage
1.24-V to 14-V Adjustable Output Voltage
Up to 1A Load Current
0.17-О© Internal MOSFET
Up to 90% Regulator Efficiency …
