说明
- DC187A-B, Demonstration Circuit is a complete DC/DC step-down regulators using the LT1374, constant frequency, high efficiency converter in 7-pin DD package. This circuit is primarily used in personal computers, disk drives, portable hand-held devices and in larger systems, as local on-board regulators. High frequency switching allows the use of small inductors, making these all surface mount solutions ideal for space-conscious systems
