Supply module:
Supply management for the IC; includes the restart and (latched) shut-down states
Protection and restart timer:
Externally adjustable timer used for delayed protection and restart timing
Enable input:
Control input for enabling and disabling the controllers; very low current consumption
when disabled
PFC controller:
Controls and protects the power factor converter; generates a 400 V (DC) boost
voltage from the rectified AC mains input with a high power factor
HBC controller:
Controls and protects the resonant converter; generates a regulated (mains isolated)
output voltage from the 400 V (DC) boost voltage
