Vin: The positive supply voltage input for the module with respect to the common ground (GND). Vout: This is the regulated output voltage from the mod- ule with respect to the common ground (GND). GND: The common node to which the input, output, and external control signals are referenced. SenseH: Provides the regulator with the ability to sense the set-point voltage directly across the load. For optimum output voltage accuracy this pin should always be con- nected to GND, even for applications that demand a relatively light load. Senset+J: When used with Sense(-), the regulation circuitry will compensate for voltage drop between the converter and the load. The pin may be left open circuit, but con- necting it to Vout will optimize load regulation.
