DC1754A - LTC3104EDE Demo Board | 2.5V to 15V input, 3.3V at 300mA (Buck) and 1.8V at 10mA (LDO)

Demonstration Circuit 1754A features the LTC®3104, a high efficiency, monolithic synchronous step-down converter using a current mode architecture capable of supplying 300mA of output current. The IC operates with a fixed frequency oscillator at 1.2MHz. The LTC3104 also incorporates a programmable LDO which can be operated from VIN, VOUT or an independent supply. The LDO can also be independently turned off or on.

The LTC3104 operates with a 2.5V to 15V input voltage range. The demo board has been designed with the main output set to 3.3V and the LDO output (VLDO) to 1.8V.
