High-density ZVS converters

Power Electronics / Power Management
The new converters retain the product series’ 22,1 x 16,5 x 6,7 mm surface-mount package profile to provide up to 20,4 W/cm³ power density and 2250 V input to output isolation. At less than 50% the size of a conventional isolated 1/16th brick, PI31xx converters provide high performance in an IC package for use in high-density system designs.
The devices utilise an advanced zero-voltage switching (ZVS) architecture and high-performance planar magnetics to enable IC-like density and greater PCB layout flexibility in space-constrained environments. Their high switching frequency (900 kHz) reduces input filter and output capacitance requirements, further reducing space requirements.
Fully equipped with a variety of programmable features, the PI31xx includes output voltage trimming, programmable soft-start capability and remote on/off enable. There is also a temperature monitor function, providing an analog output voltage proportional to the internal module temperature.
The converter is self-protected against fault conditions including input over-voltage, under-voltage lockout, over-temperature and output over-voltage. A constant current limit threshold is employed to protect against short circuit and overload conditions. All fault conditions have an auto-restart function.
When paired with 24,9 x 12,45 x 4,6 mm Picor QuietPower EMI filters, designers are afforded an end-to-end isolated DC-DC conversion and EMI filtering solution with very good density optimisation. QuietPower filters provide up to 99,5% efficiency and are designed for universal compatibility with high-frequency switching DC-DC converters from any manufacturer.
