1
Input power.
2
Mode Control.
GND for normal operation. During Start-up FPWM pin should be forced high.
3
Charge Pump 3.3V.
High side Gate drive voltage for 3.3V. This pin is to be
connected to SW3.3 through a 100nF cap. and to 5V-ALWAYS through a diode
4
High-side gate driver for 3.3V.
Connect this pin directly to the gate of an
N-channel MOSFET. The trace from this pin to the MOSFET gate should be < 1".
5
High side FET Source and Low Side FET Drain Switching Node.
node for 3.3V.
6
5V Always on linear regulator output.
with a 10μF capacitor.
Taking this pin to +5V forces PWM mode of operation. Pull to
