DC647A - LT3467ES6 | 1.2MHz, SOT-23 DC/DC Converter, 2 Circuits; Boost and SEPIC

Demonstration circuit 647 is a 1.2MHz, SOT-23 DC/DC Converter featuring the LT®3467. The demo board demonstrates two separate DC/DC converters for different application needs. The Boost Circuit is designed to convert a 5V input to 12V output at 300mA maximum load. The SEPIC Circuit generates a constant 12V/300mA output with 10V~16V variable input. Both circuits are designed to demonstrate the soft start feature, advantages of the 1.2MHz switching frequency, the internal 42V/1.1A switch, wide input voltage range and small circuit size.
