Power Boards

Collection of DC/DC converters, battery chargers and power supplies.

Power Bank 3A

Powerbank based on FP6277 boost converter with 5V and 3.3V output up to 3A.

Solar Charger

Solar powered switch-mode charger (CN3801), protector (HY2112) and 5V booster (MT3608) for LiFePO4 batteries. The charger provides maximum power point tracking (MPPT) and can easily be modified to work with LiPo batteries.

LiPo Charger (TP4056)

LiPo battery charging and protection circuit.

LiPo Charger LS (TP4056)

Li-Ion/LiPo battery charging and protection board with USB-C port and load sharing power path control.

LiPo Power Board (IP5306)

LiPo battery charger, protector and 5V booster based on the IP5306 with MicroUSB or USB-C port.

LiPo Power Board (FP6277)

Li-Ion battery charger (TP4056), protector (DW01A) and 5V/3A booster (FP6277).

LiPo Power Board (FP6298)

Li-Ion battery charger (TP4056), protector (DW01A) and 5V/2A booster (FP6298).

LIR1220 Charger (MCP73831)

Charger for LIR1220 Li-Ion batteries.

LIR2032 Charger (TP4056)

Charger for LIR2032 Li-Ion batteries.

LiFePO4 Charger (CN3058)

One cell LiFePO4 battery charger and protector.

LiFePO4 Power Board LS 3V3

Single cell LiFePO4 charging (CN3058E) and protection (HY2112) board with load sharing power path management, 3.3V output und an additional switchable output.

LiFePO4 Power Board LS 5V

Single cell LiFePO4 charger (CN3058E), protector (HY2112) and 5V booster (MT3608) board with load sharing power path management.

USB-C PD Max Trigger

Very simple USB-C Power Delivery trigger board based on the IP2721 that requests the maximum voltage (up to 20V) from the power supply.

USB-C PD Buck Converter

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.

Buck Converter (MP2307)

3A buck converter based on MP2307. Fixed output voltage can be defined via the voltage divider.

Buck Converter (LM2596)

5V/4A Buck Converter based on the LM2596.

Buck Converter (SD8942) - 78xx Replacement

Replace your old 78xx voltage regulators with this much more efficient replacement.

Boost Converter (MT3608)

Boost converter with USB plug. Fixed output voltage can be defined via the voltage divider.

Boost Converter (TPS61169)

Constant current boost converter and LED Driver with USB Plug.

SEPIC (MT3608)

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.

Low Current Boost Converter (MT3608)

Cheap and low-profile 12V boost converter based on MT3608 for low current applications (max 30mA) like high-voltage programmers.
