Product Details

Demonstration circuit 825 is a monolithic step-down DC/DC switching regulator featuring the LT1936. The demo board is optimized for 3.3V output at 1.2A from a 4.5V to 36V input or a 5V, 1.2A output from a 6.8V to 36V input. The output is selectable by placing the JP1 jumper at the 3.3V or 5V position.
