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 on this pin and the current-sense signal on the
SENSE pin.
3
NC
NA
NC pin.
4
HV
Start-up Input
For start-up, this pin is pulled high to the line input or bulk capacitor via resistors.
5
RI
Reference Setting
A resistor connected from the RI pin to GND pin provides the SG6741 with a constant
current source. This determines the center PWM frequency. Increasing the resistance
reduces PWM frequency. Using a 26K
resistor (R
I
) results in a 65kHz center PWM
frequency.
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. The internal protection circuit disables PWM output as long as V
DD
exceeds
the OVP trigger point.
8
GATE
Driver Output
The totem-pole output driver. Soft driving waveform is implemented for improved EMI.
