0.01 mm thick wire for repairing tracks on printed circuit boards. Mechanic FXS001

Step-Down DC-DC converter module based on the D36V6F12 system. Input voltage 12.2.50V, output voltage 12V (max. 600mA). Pololu 3796

This compact (0.4″ × 0.5″) switching step-down (or buck) voltage regulator takes input voltages up to 50 V and efficiently reduces them to 9 V while allowing for a maximum output current of 600 mA. It has a very low dropout, so it can be used with input voltages that are within a few hundred millivolts of its output.

Step-Down DC-DC converter module based on the D36V6F6 chip. Input voltage 6.2..50V, output voltage 6V (max. 600mA). Pololu 3793

Step-Down DC-DC converter module based on the D36V6F5 chip. Input voltage 5.2..50V, output voltage 5V (max. 600mA). Pololu 3792
