Pin Functionality
BV (extended Blanking time & input OVP)
The BV pin combines the functions of input OVP and extendable blanking time for over load protection. The input
OVP feature is to stop the switching pulse when the input line voltage is higher than the V_{OVP_ref} after the resistor
divider (Refer to Figure 3). The extendable blanking time function is to extend the built-in 20 ms blanking time for
over load protection by adding an external capacitor to ground.
FBB (Feedback & Burst entry control)
The FBB pin combines the feedback function and the burst entry/exit control. The regulation information is
provided by the FBB pin to the internal Protection Unit and the internal PWM-Comparator to control the duty cycle.
The FBB-signal is the only control signal in case of light load at the Active Burst Mode. The burst entry/ exit control
provides an access to select the entry/exit burst mode level.
CS (Current Sense)
The Current Sense pin senses the voltage developed on the shunt resistor inserted in the source of the integrated
CoolMOS™. If CS reaches the internal threshold of the Current Limit Comparator, the Driver output is immediately
switched off. Furthermore the current information is provided for the PWM comparator to realize the Current Mode.
