Driver Output
The totem-pole output driver for driving the power MOSFET.
VDD

5
Supply
Power supply.
NC

No Connection
NC pin.
SENSE
4
4
Analog Input
Current sense. This pin senses the voltage across a resistor. When the voltage reaches
the internal threshold, PWM output is disabled. This activates over-current protection.
This pin also provides current amplitude information for current-mode control.
RI

Analog
Input/Output
A resistor connected from the RI pin to ground generates a constant current source
used to charge an internal capacitor and determines the switching frequency.
Increasing the resistance reduces the amplitude of the current source and reduce the
switching frequency. A 95k
resistor, R
I
, results in a 50μA constant current I
I
and a
70kHz switching frequency.
NC

No Connection
NC pin.
FB

2
Analog Input
Feedback. The FB pin provides the output voltage regulation signal. It provides
feedback to the internal PWM comparator, so that the PWM comparator can control the
duty cycle.
GND

Supply
Ground.
