Product Details

Demonstration Circuit 164 is a constant-frequency step-down (buck) regulator using the LTC1624 switching regulator controller. DC164 is ideal for a wide range of portable, industrial, computer and communications applications. It provides up to 3A of output current at a user-selectable (via a jumper) output voltage of 2.5V, 3.3V or 5V. The input voltage can range from 4.8V to 28V (limited by the external MOSFET).
