LT1934ES6/LT1934ES6-1 Demo Board | 2 Circuits, 4.5V ≤ VIN ≤ 34V, VOUT = 3.3V/5V @ 250mA (LT1934) and 50mA (LT1934-1)

Product Details

Demonstration circuit 544 features the LT1934 and LT1934-1 wide input range micro power step-down switching regulators. There are two switching regulator circuits in DC544, the LT1934ES6 circuit designed to convert a 4.5V to 34V input voltage range to 3.3V or 5V (jumper-selectable) at 250mA output, and the LT1934ES6-1 circuit designed for the same input and output voltages but at a lighter 50mA load current. For 5V output operation, the input voltage range is 6.5V to 34V.
