Connection diagram (top view)
This pin represents the device ground and the source of the power section.
Not available for user. It can be connected to GND (pins 1-2) or left not
connected.
Supply voltage of the control section. This pin also provides the charging current
of the external capacitor during start-up time.
Control pin. The following functions can be selected:
1. current limit set point adjustment. The internal set default value of the cycle-
by-cycle current limit can be reduced by connecting to ground an external
resistor.
2. output voltage monitoring. A voltage exceeding V
shuts the IC down reducing the device consumption. This function is strobed and
digitally filtered for high noise immunity.
Control input for duty cycle control. Internal current generator provides bias
current for loop regulation. A voltage below the threshold V
burst-mode operation. A level close to the threshold V
approaching the cycle-by-cycle over-current set point.
Brownout protection input with hysteresis. A voltage below the threshold V
shuts down (not latch) the device and lowers the power consumption. Device
operation restarts as the voltage exceeds the threshold V
It can be connected to ground when not used.
High voltage drain pin. The built-in high voltage switched start-up bias current is
drawn from this pin too. Pins connected to the metal frame to facilitate heat
dissipation.
