Implementing an AC/DC Switching Adapter Port (4 x 19V,2A Port, 1 x 5V,2A Port)

Hi everyone,

I am searching for IC's and designs which would allow me to work with an AC input range of 100V to 240V and DC output at 19V,2A per port.

Switching Adapter Port Requirements:
====================================

INPUT
+++++
100-240V~ 50/60Hz

OUTPUT (4 Ports)
++++++
19V 2A per port

OUTPUT (1 Port)
++++++
5V 2A (USB Port)

So far, I have found the LM5021 as a possible PWM IC

Tks in advance for your help.
