Note 1: Absolute Maximum Ratings measured with 20MHz scope bandwidth.
Note 2: LX3 has clamp diodes to PGND and IN3. If continuous current is applied through these diodes, thermal limits must be observed.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(Circuit of Figure 2, VIN = 12V, VCC = VDD = VIN3 = SHDN = PGD_IN = 5V, VDDIO = 1.8V, OPTION = GNDS_ = AGND = PGND,
FBDC_ = FBAC_ = OUT3 = CSP_ = CSN_ = 1.2V, all DAC codes set to the 1.2V code, TA = 0°C to +85°C, unless otherwise noted.
Typical values are at TA = +25°C.)
