Analog Devices LTM8052EV DEMO CIRCUIT 1866A

See the Analog Devices demo board DC1866 featuring the LTM8052, a 36-volt input step down micro module regulator with adjustable output voltage and output current limit. This means the LTM8052 will regulate either the user set output voltage or the output current, which can be a useful protection feature as this video demonstrates.
