LM2621SNVS033D –MAY 2004–REVISED NOVEMBER 2015
LM2621 Low Input Voltage, Step-Up DC-DC Converter Features 3 DescriptionThe LM2621isa high efficiency, step-up DC-DC Small VSSOP8 Package (Half the Footprintof switching regulator for battery-powered and low inputStandard 8-Pin SOIC Package) voltage systems.It accepts an input voltage between• 1.09-mm Package Height 1.2V and14V and convertsit intoa regulated output Upto 2-MHz Switching Frequency voltage. The output voltage canbe adjusted between
1.24V and14V.It hasan internal 0.17-Ω N-Channel• 1.2-Vto 14-V Input Voltage MOSFET power switch. Efficiencies upto 90% are• 1.24-Vto 14-V Adjustable Output Voltage achievable using the LM2621.• Upto 1A Load Current The high switching frequency (adjustable upto2• 0.17-Ω Internal MOSFET MHz)of the LM2621 allows for tiny surface mount• Upto 90% Regulator Efficiency inductors and capacitors. Because of the unique
constant-duty-cycle gated oscillator topology very• 80-µA Typical Operating Current high efficiencies are realized overa wide load range.• < 2.5-µA Specified Supply CurrentIn Shutdown The supply currentis reducedto 80 µA becauseof
the BiCMOS process technology. In the shutdown
2 Applications mode, the supply currentis less than 2.5 µA. PDAs, Cellular Phones The LM2621is availableina VSSOP-8 package.• 2-Cell and 3-Cell Battery-Operated Equipment This package uses half the board areaofa standard
8-pin SOIC and hasa heightof just 1.09 mm.• PCMCIA Cards, Memory Cards Flash Memory Programming
