Power Integrations RDK-928 60 W PSU for Evaluating MinE-CAP

Power Integrations’ MinE-CAP IC dramatically reduces the size of the required input capacitors of a power supply, without compromising output ripple or operating efficiency. MinE-CAP also precisely manages inrush current when the supply is connected to the mains, eliminating the need for dissipative NTCs or large slow-blow fuses as I2t stress on input components is dramatically reduced.

Partnered with Power Integrations’ InnoSwitch IC family, MinE-CAP allows for the lowest component count, ultra-compact AC-DC converters without redesign of the transformer. This enables an adaptor size reduction of up to 40% whilst avoiding the EMI and dissipation challenges associated with traditional high-frequency SMPS designs. The device itself comes in a modest 11.32 x 5.67 x 1.94 mm (including leads) MinSOP-16A package.

MinE-CAP is designed for use in applications requiring an extended wide-range input (90-350 VAC), such as consumer electronics and laptop PSUs, USB chargers, and home appliances. MinE-CAP also offers protection against output open loop, output overvoltage, output short circuit, output undervoltage, and overtemperature; the operating range of the MinE-CAP is -40°C to +150°C.

Power Integrations’ RDK-928 Reference Design Kit provides a readily available product for engineers to see the MinE-CAP in action, as well as their InnoSwitch4-CZ and ClampZero devices. The RDK-928 is a 60 W ultra-compact USB PD 3.0 charger designed for mobile phones and laptop computers with 93% efficiency. It uses a flyback topology and accepts a universal input (90-265 VAC) with a variable output voltage of 5, 9, 15, or 20 VDC, all at 3 A max current.

If you would prefer to evaluate MinE-CAP in a different way, Power Integrations provides many reference designs that can be built by the engineer to test. Please specify if you would prefer this option when applying for this board.
