Product Summary
The LM2621MMX/NOPB is a high efficiency, step-up DC-DC switching regulator for battery-powered and low input voltage systems. It accepts an input voltage between 1.2V and 14V and converts it into a regulated output voltage. The output voltage can be adjusted between 1.24V and 14V. It has an internal 0.17W N-Channel MOSFET power switch. Efficiencies up to 90% are achievable using the LM2621MMX/NOPB. The applications of the LM2621MMX/NOPB include PDAs, Cellular Phones, 2-Cell and 3-Cell Battery-Operated Equipment, PCMCIA Cards, Memory Cards, Flash Memory Programming, TFT/LCD Applications, 3.3V to 5.0V Conversion, GPS Devices, Two-Way Pagers, Palmtop Computers.
