ML4819, Power Factor and PWM Controller Combo

The ML4819 is a complete boost mode Power factor Controller (PFC) which also contains a PWM controller.

The PFC circuit is similar to the ML4812 while the PWM controller can be used for current or voltage mode control for a second stage converter.

Since the PWM and PFC circuits share the same oscill
