PACKAGE/ORDER INFORMATION

The

● denotes specifications which apply over the full operating

temperature range, unless otherwise noted specifications are at TA = 25°C, VIN = 12V, CTL and GND = 0V. Current into a pin is positive

and current out of a pin is negative. All voltages are referenced to GND, unless otherwise specified.
