Description

  • Circuit shows LT3724, 15V to 12V,2A SEPIC converter configured to use the 12V output voltage to back drive VCC. The LT3724 uses a 200kHz fixed-frequency current-mode architecture. An internal high voltage bias regulator allows for simple startup and biasing, and it can be back driven by the output to increase supply efficiency and lower power dissipation in the IC

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.
