Pin Assignment
The XN1042 is offered in DIP and SOP
Packages shown as below.
Terminal Definition
Pin Num Pin Name I/O
Description
1
GND
P Ground
2
FB
I
Feedback input pin. The PWM duty cycle is determined by voltage level
into this pin and the current-sense signal at Pin 6.
3
VIN
I
Connected through a large value resistor to rectified line input for Startup IC
supply and line voltage sensing.
Internal Oscillator frequency setting pin. A resistor connected between RI
4 RI I and GND sets the PWM frequency.
5 RT I Temperature sensing input pin. Connected through a NTC resistor to GND
6
SENSE
I Current sense input pin. Connected to MOSFET current sensing resistor node.
7
VDD
P IC DC power supply pin.
8
GATE
O Totem-pole gate drive output for the power MOSFET.
Note: Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only,
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied.
Exposure to absolute maximum-rated conditions for extended periods may affect device reliability.
