LT1959CR Demo Board, 4.5A Switch, 500kHz Step-Down Regulator, 5V to 15Vin, 1.8Vout @ 4A

Demonstration circuit is complete DC/DC step-down regulator using the LT1959 constant frequency, high efficiency converter in 7-pin DD (DC356). These circuits are primarily used in personal computers, disk drives, portable handheld devices and, in larger systems, as local on-board regulators. High frequency switching allows the use of small inductors, making this all surface mount solution ideal for space conscious systems
