PACKAGE/ORDER INFORMATION

The

● denotes specifications which apply over the full operating

temperature range (Note 4), otherwise specifications are at TA = 25°C. VDCIN = 20V, VBAT = 12V unless otherwise noted.

ELECTRICAL CHARACTERISTICS

TJMAX = 125°C, θJA = 90°C/W

EXPOSED PAD (PIN 25), GND AND PGND SHOULD BE CONNECTED

TOGETHER WITH A LOW OHMIC CONNECTION.
