WEBENCH® Tools/PMP6910: PMP6910

Part Number: PMP6910

Tool/software: WEBENCH® Design Tools

Hi,

My application is an LED driver solution for universal AC input (85-264V) and output is wide range LED Vf (forward voltage) from 20-50 and max. LED current = 1.5A i.e. constant current topology.

I have found the PMP6910 which is most close to my need and consider to build my application by adjust and optimize this reference design. 

Firstly I would like to adjust the AC/DC buck converter block to achieve an output of 60VDC 1.5A. then use LED driver TPS92512VH or LM3409HV. On top of that there is also an MCU to control the LED Driver with PWM.

It is not possible to simulate the design on WEB Bench there is only a Design Calculator for the UCC28600 available and I am not sure that I can optimize my design to achieve an efficiency >90 % 

This is my first time using TI solution and in LED light  and need some expert support!

Mr.
