ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for the LX1562/1563 with 0°C
≤ T
A ≤ 100°C; VIN=12V. Low duty cycle pulse
testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
