ADP1074ARWZ

ADP1074 is an isolated, synchronous forward controller with active clamp and iCoupler designed for isolated DC to DC power supplies. With the integrated isolators and metal-oxide semiconductor field effect transistor (MOSFET) drivers on both the primary and the secondary side, this offers a compact system level design and yields a higher efficiency than a nonsynchronous forward converter at heavy loads. 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. Typical applications are 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/optical routing, power modules.

• Reduces system design complexity, cost, and component count and improves overall system reliability
• Current mode controller for active clamp forward topology, programmable slope compensation
• Integrated 1A primary side MOSFET driver for power switch and active clamp reset switch
• Frequency synchronization, programmable maximum duty cycle limit
• Integrated error amplifier and <lt/>1% accurate reference voltage
• Programmable soft start, smooth soft start from precharged load, programmable dead time
• Power saving light load mode using MODE pin, cycle-by-cycle input overcurrent protection
• Protection features such as short circuit, output overvoltage, and overtemperature protection
• Tracking function from secondary side, remote (secondary side) shutdown/reset function
• 24-lead standard small outline package (SOIC-W), -40°C to +125°C temperature rating
