ADP1071-2ACCZ-R7

Overview

The ADP1071-2ACCZ-R7 is an isolated synchronous flyback controller from Analog Devices, designed for high-efficiency power conversion. It features a fixed switching frequency range of 50 kHz to 600 kHz and supports a maximum duty cycle of 85%. The device operates within an input voltage range of 4.5 V to 36 V, with a typical operating supply voltage of 12 V. It is housed in a 24-pin LGA package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates iCoupler technology for isolated feedback control without external optocouplers
• Supports synchronous rectification to enhance converter efficiency
• Utilizes PWM current mode control for precise regulation

Applications

• Isolated DC-to-DC power supplies
• Industrial control systems
• Telecommunications equipment
