Description
1 INV
Inverting input of the error amplifier. INV is connected to the converter output via a resistive divider. This pin
is also used for over-voltage clamping and open-loop feedback protection.
2 COMP
The output of the error amplifier. To create a precise clamping protection, a compensation network between
this pin and GND is suggested.
3 MOT
A resistor from MOT to GND is used to determine the maximum on-time of the external power MOSFET. The
maximum output power of the converter is a function of the maximum on-time.
4 CS
Input to the over-current protection comparator. When the sensed voltage across the sense resistor reaches
the internal threshold (0.82V), the switch is turned off to activate cycle-by-cycle current limiting.
5 ZCD
Zero Current Detection. This pin is connected to an auxiliary winding via a resistor to detect the zero crossing
of the switch current. When the zero crossing is detected, a new switching cycle is started. If it is connected
to GND, the device is disabled.
6 GND
The power ground and signal ground. Placing a 0.1µF decoupling capacitor between the VCC
and GND pins
is recommended.
7
GD
Totem-pole driver output to drive the external power MOSFET. The clamped gate output voltage is 16.5V.
8
VCC
Driver and control circuit supply voltage.
