Rhea-AI Summary
Power Integrations has announced the release of DER-937, a reference design for a 100W USB Power Delivery charger, highlighting a remarkably low component count of just 117. This new design utilizes the InnoSwitch3-PD and HiperPFS-4 ICs, achieving efficiency levels exceeding 93%, with less than 40 mW no-load power at 230 VAC. This innovative approach not only simplifies the design process but also reduces manufacturing costs and space requirements. The DER-937 report includes comprehensive specifications and is available for download on the Power Integrations website.

DER-937 charger achieves over 93% efficiency.
Only 117 components used, significantly reducing BOM count.
Less than 40 mW no-load power consumption at 230 VAC.
Simplifies component sourcing and design time for manufacturers.
Negative
None.
DER-937 leverages highly integrated boost PFC and GaN flyback switcher ICs to implement 100 W USB PD charger using only 117 components
SAN JOSE, Calif.--(BUSINESS WIRE)--
Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today published a new reference design that describes a USB Power Delivery (PD) charger with exceptional performance and very low component count. Based around Power Integrations' new InnoSwitch™3-PD PowiGaN™ flyback switcher and HiperPFS™-4 PFC controller ICs, the DER-937 report contains the power supply specification, schematic, PCB layout, bill of materials, detailed magnetics specifications and performance data of a power factor corrected (PFC) 100 W USB PD 3.0 + Programmable Power Supply (PPS) charger using only 117 components.

Aditya Kulkarni, senior product marketing engineer at Power Integrations, said: "This USB PD charger design reaches efficiency levels in excess of 93%, including input, PFC and flyback stages. Its no-load performance is also excellent – the circuit requires less than 40 mW no-load input power at 230 VAC. BOM count is approximately half that of conventional designs, saving space, reducing design time and simplifying component sourcing for high-volume manufacture of slim, ultra-compact OEM and aftermarket chargers."
DER-937 uses two recently introduced ICs from Power Integrations. The InnoSwitch3-PD INN3870C off-line quasi-resonant flyback switcher combines a USB Type C and USB PD controller, high-voltage PowiGaN gallium-nitride switch, synchronous rectification and FluxLink™ feedback. The HiperPFS-4 PFS7628C PFC controller IC, available with an integrated Qspeed™ low-reverse-recovery-charge (Qrr) boost diode, delivers greater than 98% efficiency across the full load range.
