CH-2 differential current sense inputs. The CSA2 pin connects to the CH-2 power inductor. The CSB2 pin  
connects to the circuit breaker or directly to the LV-Port if the circuit breaker is not used. The CH-2 current sense  
resistor is placed between these two pins.

No connect  
Internally connected to VIN the pin through a cutoff switch. When the controller is shut down, VINX is  
disconnected from VIN, opening the current leakage path. When the controller is enabled, VINX is connected to  
VIN and serves as the pullup supply for the RC ramp generators at the RAMP1 and RAMP2 pins. VINX also  
pulls up the OVPA pin through an internal 3-MΩresistor.
