Power Integrations offers design example report for high-efficiency 900W power supply
Power Integrationscontact supplier
DER-274 (for HiperPFS)
Power Integrations has published DER-274, a new design example report that describes a 900W power supply with 97 per cent efficient active power factor correction (PFC), designed for use in white goods, blowers, motor control drives and computing applications.
Based on the company’s HiperPFS family of high-efficiency PFC controller ICs, this design is claimed to offer a smaller, lighter and higher-efficiency alternative to passive PFC systems, which also reduces component count and board footprint.

Power Integrations has launched its Linkswitch-3 series of integrated monolithic switching ICs. The devices are claimed to deliver accurate primary-side regulation for chargers and adapters up to 10W, making them suitable for smartphones, tablets and other mobile devices, particularly those subject to 30mW no-load limitations, such as upcoming mandatory US DoE EPS efficiency regulations and EU CoC Tier 2 guidelines.
This document from Power Integrations is an engineering report describing a non-isolated LED driver (power supply) utilising a LNK458KG from the Linkswitch-PL series of devices.
The Linkswitch-PH has been developed to cost-effectively design a single-stage power-factor-corrected LED driver with primary-side constant-current control.
This design idea presents the schematic for a CV/CC power supply for LED driver applications using the Linkswitch-II LNK605DG.
The power supply shown in this design idea uses a Linkswitch-TN device in a boost converter configuration to deliver a constant current of 20mA from a single positive voltage of 554VDC.
