Power Integrations RDK-928 Reference Design Kit

Power Integrations RDK-928 Reference Design Kit demonstrates a 60W USB PD 3.0 Power Supply circuit based on the INN4073C InnoSwitch™ 4-CZ Flyback Switcher and the CPZ1062M ClampZero™ Active Clamp IC. The InnoSwitch4-CZ Switchers combine with the ClampZero Active Clamp ICs to dramatically improve the efficiency of flyback power converters, especially those requiring a compact form factor. Power Integrations RDK-928 Reference Design Kit provides a 5V, 9V, 15V, or 20V output at 3A. This design shows the high power density and efficiency possible due to the high level of integration of the INN4073C InnoSwitch4-CZ and the CPZ1062M ClampZero Active Clamp IC. The Reference Design Kit also incorporates the input capacitor volume-reduction capabilities of the MIN1072M MinE-CAP IC.
