6 / 31 page LM2642 SNVS203I – MAY 2002 – REVISED APRIL 2013 www.ti.com ELECTRICAL CHARACTERISTICS (continued) Unless otherwise specified, VIN = 15V, GND = PGND = 0V, VLIN5 = VDD1 = VDD2. Limits appearing in boldface type apply over the specified operating junction temperature range, (-20°C to +125°C, if not otherwise specified). Specifications appearing in plain type are measured using low duty cycle pulse testing with TA = 25°C (1), (2). Min/Max limits are specified by design, test, or statistical analysis.
