This video introduces Analog Devices’ new family of isolated DC/DC controllers that feature an integrated closed loop feedback path using iCoupler™ technology.
Watch this video to see Analog Devices' ADP1074 – an isolated, synchronous forward controller with active clamp and iCoupler™ – demonstrated, as well as the ADP1071 flyback version.
The ADP1074 is a current mode, fixed frequency, active clamp, synchronous forward controller designed for isolated dc to dc power supplies. Analog Devices proprietary iCouplers™ are integrated in the ADP1074 to eliminate the bulky signal transformers and optocouplers that transmit signals over the isolation boundary. Integrating the iCouplers™ reduces system design complexity, cost, and component count and improves overall system reliability. With the integrated isolators and metal-oxide semiconductor field effect transistor (MOSFET) drivers on both the primary and the secondary side, the ADP1074 offers a compact system level design and yields a higher efficiency than a non-synchronous forward converter at heavy loads.
The ADP1071-1 is a pulse-width modulation (PWM) current mode fixed frequency synchronous flyback controller designed for isolated dc-to-dc power supplies. Analog Devices proprietary iCouplers™ are integrated in the ADP1071-1 to eliminate the bulky signal trans-formers and optocouplers that transmit signals over the isolation boundary. Integrating the iCouplers reduces system design complexity, cost, and component count and improves overall system reliability. With the integrated isolators and metal-oxide semiconductor field effect transistor (MOSFET) drivers on both the primary and the secondary side, the ADP1071-1 offers a compact system level design and yield a higher efficiency than a diode rectified flyback converter at heavy loads.
