This project is a step up DC to DC power converter able to convert 2.4V – 5V to 5Vdc.
This project has been designed around Texas Instruments LM2623 IC, The LM2623 is a high efficiency, general purpose step-up DC-DC switching regulator for battery powered and low input voltage systems. It accepts an input voltage between 2.4V to 12V volts and converts it into 5V DC. Efficiencies up to 90% are achievable with the LM2623.
- Good Efficiency over a very wide load range
- Very low output voltage ripple
- 2.4V to 5V (Possible Input Supply up to 14V operating voltage)
- 5V output voltage (Other output voltages possible by changing R3 and R4)
- Hand held instruments
- Cameras, PDA, Cellphones
- White LED driver
