Analog Devices, Inc. Isolated, Synchronous Forward Controller with Active Clamp and iCoupler® ADP1074ARWZ-RL

Description
Product Details The ADP1074 is a current mode, fixed frequency, active clamp, synchronous forward controller designed for isolated dc to dc power supplies. Analog Devices proprietary i Couplers® are integrated in the ADP1074 to eliminate the bulky signal trans-formers and optocouplers that transmit signals over the isolation boundary. Integrating the i Couplers 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 primary side pins provide functions for programming the switching frequency, maximum duty cycle, external frequency synchronization, and slope compensation. The secondary side pins provide functions for differential output voltage sensing, overvoltage, power good, tracking, and programmable light load mode setting. The feedback signal and timing of synchronous rectifier pulse-width modulations (PWMs) are transmitted from primary to secondary or from secondary to primary sides through the iCouplers using a proprietary transmission scheme. The ADP1074 also offers features such as input current protection, undervoltage lockout (UVLO), precision enable with adjustable hysteresis, overtemperature protection (OTP), and power saving light load mode (LLM). Applications Isolated dc-to-dc power conversion Intermediate bus voltage generation Telecom, industrial Base station and antenna RF power Small cell PoE powered device Enterprise switches/routers Core/edge/metro/opti cal routing Power modules
