9V @ 45mA Boost Converter Output with Input 2.1V to 5.5V
The project shown here is a boost converter that provides 9V DC output from 2.1V to 5.5V input. It is a good choice for battery-operated devices where the converter can be connected to 2x 1.5V, 3 x 1.5V Battery, 1 x Li-ion, 2 x NICAD, 2 x NIMH, and provide 9V Output. The board is built using BD8158FVM chip and the pin configuration is the same as TO220 78xx LDO and the size is also the same. Output is very accurate and provides approx. 85% efficiency at an operating frequency of 1.2Mhz.
Features
- Input 2.1V to 5.5V (2 X NIMH Battery, 2 X NICAD Battery, 1X Li-Ion Battery 3.6V, 2X AA/AAA battery)
- 3 Pin Header Pitch 2.54MM for Output and Input (Pin Configuration same as TO220 LDO Such as LM7805)
- Output 9V DC
- Output Current 45mA
- 85% Efficiency
- Output Voltage +/-1%
- Current Mode PWM System
- Built-In Under-Voltage Lockout Protection Circuit
- Built-In Over-Current Protection Circuit
- Built-In Thermal Shutdown Circuit
- PCB Dimensions 20.16 x 9.05mm
