Description
Ground . SenseFET source terminal on the primary side and internal control ground.
Positive Supply Voltage Input . Although connected to an auxiliary transformer winding,
current is supplied from pin 5 (V STR ) via an internal switch during startup ( see Internal Block
Diagram Section ). Once V CC reaches the UVLO upper threshold (12 V), the internal startup
switch opens and device power is supplied via the auxiliary transformer winding.
Feedback Voltage . The non-inverting input to the PWM comparator, it has a 0.4 mA current
source connected internally, while a capacitor and opto-coupler are typically connected
externally. There is a delay while charging external capacitor C FB from 2.4 V to 6 V using an
internal 5 μA current source. This delay prevents false triggering under transient conditions, but
still allows the protection mechanism to operate under true overload conditions.
Peak Current Limit . Adjusts the peak current limit of the SenseFET. The feedback 0.4 mA
current source is diverted to the parallel combination of an internal 6 k ? resistor and any
external resistor to GND on this pin to determine the peak current limit.
Startup . Connected to the rectified AC line voltage source. At startup, the internal switch
supplies internal bias and charges an external storage capacitor placed between the V CC pin
and ground. Once V CC reaches 12 V, the internal switch is opened.
Drain . Designed to connect directly to the primary lead of the transformer and capable of
switching a maximum of 650 V. Minimizing the length of the trace connecting these pins to the
transformer decreases leakage inductance.
