LC filter for DC 0-50V 3A power supply

8-channel voltage level converter module with an input voltage of 12 V and an output voltage of 3.3 V. Unidirectional, based on resistor dividers. Numato Lab NLVD00008

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 9 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors.

A two-channel DC motor controller with a UART TTL interface. It is powered from 4.5 V to 48 V and can deliver up to 1.8 A per motor. Board with soldered connectors. Pololu 5066

The compact (0.4″ × 0.5″) D24V5F1 synchronous buck voltage regulator takes input voltages between 3 V and 36 V and efficiently reduces them to 1.8 V while allowing for a maximum output current of 500 mA. This regulator offers typical efficiencies between 75% and 90%. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.
