Function
Description
1
GND
Ground
Ground.
2
FB
Feedback
The signal from the external compensation circuit is fed into this pin. The PWM duty cycle is
determined in response to the signal from this pin and the current-sense signal from Pin 6. If FB
voltage exceeds the threshold, the internal protection circuit disables PWM output after a
predetermined delay time.
3
VIN
Start-Up Input
For start-up, this pin is pulled high to the rectified line input via a resistor. Since the start-up
current requirement of the SG5841/J is very small, a large start-up resistance can be used to
minimize power loss.
4
RI
Reference
Setting
A resistor connected from the RI pin to GND pin provides the SG5841
/J
with a constant current
source. This determines the center PWM frequency. Increasing the resistance reduces PWM
frequency. Using a 26K
resistor results in a 65KHz center PWM frequency.
5
RT
Temperature
Detection
For over-temperature protection. An external NTC thermistor is connected from this pin to the
GND pin. The impedance of the NTC decreases at high temperatures. Once the voltage of the
RT pin drops below a fixed limit, PWM output is disabled.
6
SENSE
Current Sense
Current sense. The sensed voltage is used for peak-current-mode control and cycle-by-cycle
current limiting.
7
VDD
Power Supply
Power supply. If V
DD
exceeds a threshold, the internal protection circuit disables PWM output.
8
GATE
Driver Output
The totem-pole output driver for the power MOSFET, which is internally clamped below 18V.
