130W HiperPFS -3 Posted by: george08 on Tue, 04/02/2019 I would like to design a 130W led driver and have found that HiperPfc-3 series is apt for the application. I am having some doubt regarding the Vcc supply and also seeking for the reference design. Is there anyone to help me 回應 Hi, The HiperPFS-3 family of devices are intended for applications requiring power factor correction (PFC front-end). You may want to look at below link for a reference design with CV/CC functionality (suitable for LED lighting application). https://ac-dc.power.com/design-support/reference-designs/design-examples/der-484-300-w-forward-power-supply/ Regards.
