RCB
Phase C/D current controller -Time set pin.
Use this pin to set the desired Off-time of the switching current controller.
A 470pF capacitor and 56k
Ω resistor are internally connected between this pin
and GND1 (Pin13), giving a 16 µs -time.
13
GND1
Logic stage GND. Return path for the logic signals and VSS (pin1) supply
voltage.
14
GND2
Power stage GND. Return path for the power stage and VS (pin19) supply
voltage.
