ADP1071 Isolated Flyback Controllers

Analog Devices Inc. ADP1071 Isolated Synchronous Flyback Controllers with integrated iCouplers^® are Pulse-Width Modulation (PWM) current mode fixed frequency controllers designed for isolated DC-to-DC power supplies. These controllers come in ADP1071-1 and ADP1071-2 variants. The proprietary iCouplers are integrated into the ADP1071-1/ADP1071-2 controllers to eliminate the bulky signal transformers and optocouplers that transmit signals over the isolation boundary. This integration improves overall system reliability and reduces system design complexity, cost, and component count.
