3.3V-ALWAYS
Input power.
3.3V Always on linear regulator. Load current on pins 2 and 6 must not exceed
50mA total. This pin should be decoupled to ground with a 10µF capacitor.
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
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".
High side FET Source and Low Side FET Drain Switching Node. Switching
node for 3.3V.
5V Always on linear regulator output. The sum of the load currents on pins 2
and 6 must not exceed 50mA total. This pin should be decoupled to ground with
a 10µF capacitor.
