Evaluation board based on HVLED815: 15 W European-wide high power factor LED driver with primary-side current regulation

EVLHVLED815W15

Overview

The LED driver board is based on a flyback topology using the STMicroelectronics^®HVLED815PF device.

The HVLED815PF device is a high voltage primary switcher intended for operating directly from the rectified mains with minimum external parts and enabling high power factor (> 0.95) to provide an efficient, compact and cost effective solution for LED driving. It combines a high-performance low voltage PWM controller chip and an 800 V, avalanche rugged Power MOSFET, in the same package. There is no need for the optocoupler thanks to the patented primary sensing regulation (PSR) technique. The device assures protection against LED string fault (open or short).

Main features

15 W LED driver
Single stage HPF flyback
Primary side regulation - no optocoupler
Power factor > 0.95
LED driver efficiency > 84%

CCS V5 local variable problem
When using C2000 Launchpad, the local variables in the function cannot be controlled, such as Uint16 i ; for ( i = 0 ; i < 1024 ; i++ ){} ... the variable i changes only once, and then jumps out of th
About 51 single chip microcomputer control DC motor speed regulation
As shown in the figure above, please help me write a program in Keil u4 to control the speed of the motor. Forward 1 represents a forward speed, and forward 2 represents a forward second speed (the sp
Who has a pudn account? Can you help me download the program?
It would be best if you can download all of them. If not, download them in order. http://www.pudn.com/downloads54/sourcecode/windows/control/button/detail188095.html http://www.pudn.com/downloads62/so
Help with microvolt-level DC voltage amplification
I want to amplify a 100uV-2mV signal. I used op07cp and first used a subtraction circuit to collect and amplify it, but it didn't work. Later, I used an instrument amplifier circuit to experiment, but
Problems with configuring multiple registers in FPGA
As the title says, I would like to ask you how to configure multiple groups of FPGA registers by sending data through the serial port of the host computer, and the number of bits of the registers is r
