The USB Power Filter reduces noise and ripple on the 5V power rail through a combination of different low-pass filters.
With the USB-PD Source, old power supplies can be transformed into modern fast charging adapters with a USB Type-C output port and an output power of up to 18W. The device masters the most common fast charging protocols (PD2.0, BC1.2, QC2.0, QC3.0, FCP, AFC e.g. for Apple, Samsung, Huawei) and can offer different voltages with high currents (5V/3A, 9V/2A, 12V/1.5A).
With the USB PD Decoy, a USB Type-C PD power adapter can be used as a power supply with the option of selecting different output voltages via DIP switches. It is based on the cheap and easy-to-use CH224K multi fast charging protocol power receiving chip.
Very simple USB Type-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 Type-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.
A simple testing device to verify the presence and continuity of power and data lines in USB charging cables.
3A buck converter based on MP2307. Fixed output voltage can be defined via the voltage divider.
5V/4A Buck Converter based on the LM2596.
Replace your old 78xx voltage regulators with this much more efficient pin-compatible buck converter.
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 SEPIC (Single Ended Primary Inductance Converter) non-inverting buck/boost converter 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.
