Texas Instruments LM2623EV Evaluation Board

Texas Instruments LM2623EV Evaluation Board is designed to evaluate the LM2623 general-purpose, gated oscillator-based DC/DC boost converter. TI LM2623EV Evaluation Board is programmed for a 5V output running off a two-cell power supply. Texas Instruments LM2623 DC/DC boost converter can run from a low input voltage and produce a regulated output voltage with low ripple. This DC/DC boost converter is designed for use with a wide variety of applications, including cameras, pagers, and cell phones.
