Resonant power supply controller IC with PFC for LED lighting

7. Functional description

7.1 Overview of IC modules

The functionality of the SSL4120 is grouped as follows:

• Supply module:

Supply management for the IC. Includes the restart and (latched) shut-down states

• Protection and restart timer:

An externally adjustable timer used for delayed protection and restart timing

• Enable input:

Control input for enabling and disabling the controllers. When disabled has very low

current consumption

• PFC controller:

Controls and protects the power factor converter. Generates a 400 V (DC) boost

voltage Vboost from the rectified AC mains input with a high PF

• HBC controller:

Controls and protects the resonant converter. generates a regulated, mains isolated

output voltage from the 400 V (DC) boost voltage Vboost

Figure 1 shows the block diagram of the SSL4120. A typical application is shown in

Figure 19.
