The ZC1649-AED is a no-opto flyback transformer designed for use with the MAX17690 isolated flyback controller, operating at 170 kHz with a 20-56 V input voltage range. It provides a 24 V, 0.36 A output with a 1:0.875 turns ratio, 31.40 μh primary inductance at 0 A, and 0.60 μh maximum leakage inductance. The transformer features 1500 Vrms isolation between windings, a maximum operating temperature of +125°C, and is rated for AEC-Q200 qualification at +125°C. It uses ferrite core material and is packaged in a 13″ reel with 500 units per reel, using 24 mm wide embossed plastic tape. The part weighs 1.5 g and supports three 40-second reflows at +260°C. It meets MSL 1 moisture sensitivity requirements.
These flyback transformers are designed to work with the MAX17690 60 V, no-opto isolated flyback controller from Analog Devices. They have no auxiliary winding and offer the greatest efficiency, lowest cost, and smallest size for synchronous isolated DC-DC power converters. They operate with a 10 – 28 V or 20 – 56 V input voltage range and generate three different outputs. These parts have a maximum height of just 6.5 mm, significantly lower than other parts recommended for the same chipset.
