LT1105 Offline Switching Regulators
Analog Devices Inc. LT1105 Offline Switching Regulators are designed for high input voltage applications using an external FET switch. The LT1105 features a totem pole output that drives the gate of an external FET. The regulators have a unique design that eliminates the need for an optocoupler while still providing ±1% load and line regulation in a magnetic flux-sensed converter. This simplifies the design of offline power supplies and reduces the number of components that must cross the isolation barrier to one, the transformer. These regulators are used in fully isolated multiple outputs and distributed power conversion networks.
