Pin Function Description
External capacitor.
on-time pulse width circuit. Careful layout of this pin is critical to system performance.
See Applications Information for details.
Analog V
cc
.
Power supply for regulator control circuitry and voltage reference. Connect to
system 5V supply and decouple to ground with 0.1μF ceramic capacitor.
High side current feedback.
Pins 3 and 4 are used as the inputs for the current feedback
control loop and as the short circuit current sense points. Careful layout of the traces from
these pins to the current sense resistor is critical for optimal performance of the short circuit
protection scheme. See Applications Information for details.
Low side current feedback.
See Applications Information for details.
Voltage feedback.
Using two external resistors, this pin sets the output voltage level for the
switching regulator.
Power Ground.
Connect to a low impedance ground. See Application Information for
details.
MOSFET driver output.
Connect this pin to the gate of the N-channel MOSFET Q1 as
shown in Figure 12. The trace from this pin to the MOSFET gate should be kept as short as
possible (less than 0.5"). See Applications Information for details.
Power V
cc
.
Power supply for DRV output driver. Connect to system 12V supply with R-C
filter shown in Figure 12. See Applications Information for details.
A 180pF capacitor is connected to this pin as part of the constant
