Single cell LiFePO4 charging (CN3058E) and protection (HY2112) board with load sharing power path management, 3.3V output und an additional switchable output.
Single cell LiFePO4 charger (CN3058E), protector (HY2112) and 5V booster (MT3608) board with load sharing power path management.
Very simple USB-C Power Delivery trigger board based on the IP2721 that requests the maximum voltage (up to 20V) from the power supply.
A slightly different approach to USB-C power delivery by combining a PD maximum voltage trigger (IP2721, up to 20V) and a buck converter (MP2307). The output voltage can be selected via the voltage divider (R5 + R6). The maximum output current is 3A.
3A buck converter based on MP2307. Fixed output voltage can be defined via the voltage divider.
5V/4A Buck Converter based on the LM2596.
Boost converter with USB plug. Fixed output voltage can be defined via the voltage divider.
Constant current boost converter and LED Driver with USB Plug.
Simple single ended primary inductance converter (SEPIC) based on the MT3608 with a fixed output voltage selectable by the resistor values of the voltage divider.
Cheap and low-profile 12V boost converter based on MT3608 for low current applications (max 30mA) like high-voltage programmers.
