ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VDD = 14V, VOUT = 5V, LP = 1.5mH, NP = 140, NS = 7, NA = 19, TA = 25°C, unless otherwise specified.)
: Do not exceed these limits to prevent damage to the device. Exposure to absolute maximum rating conditions for long periods may
affect device reliability.
