2 in 1 DC-DC Step-Down & Step-Up Converter Module

1. Fixed Output 3.3 V + -4%

2. Input Voltage Range: 1.8 ~ 5 V (You can use two of this module to use the 1.2 V NiMH batteries).

3. Long maximum time 100mA output current

4. Short Maximum output time space 150mA current

5. working frequency 1.2 MHz.

6. Short Circuit Protection

7. No Load Input Current: 0.65mA

8. 2.54mm pin pitch, for MCU Development Board Friendly Test Plate

9. Excluding Pin Size 11mm x 7.62mm x 4.5mm (Small)

10. Weight: about 0.5g

this is a DC-DC voltage converter module, it should be noted when using:

1. Input voltage can not be higher than the maximum input range

2. Output power can not be greater than the maximum load for a long time

3. Input power must be greater than the output power, because the power consumption of the module itself
