Analog Devices, Inc. Flyback controller with integrated isolation and SR drive ADP1071-2ARWZ

Product Details The ADP1071-1 is a PWM current mode fixed frequency synchronous flyback controller designed for isolated DC-to-DC power supplies. ADI’s proprietary i Couplers are integrated in the ADP1071-1/ADP1071-2 to eliminate the bulky signal transformers and opto-couplers while reducing system design complexity, cost and component count, and improving overall system reliability. With the integrated isolators and drivers on both the primary and secondary, the ADP1071-1/ADP1071-2 offers a compact system level design and yields a higher efficiency than a diode rectified flyback converter at heavy loads. Output regulation is achieved by sensing the output voltage on the secondary side, where the feedback and the PWM signals are transmitted between the primary and secondary through the i Couplers. The ADP1071-1/ADP1071-2 is offered in the 16L SOIC_W with an isolation voltage rating of 5 kVRMS. The ADP1071-2 is designed for isolated DC-DC applications for low input voltage applications, and the ADP1071-1 targets high input voltage applications, where the DC input voltage can exceed 60V. The ADP1071-1/ADP1071-2 offers features such as input current protection, output over-voltage protection (OVP), under voltage lockout (UVLO), precision enable with adjustable hysteresis, over temperature protection (OTP) and light-load power saving mode (LLM).
