Quad, High-Voltage EL Lamp Driver
with I2C Interface
ELECTRICAL CHARACTERISTICS (continued)
(VDD = +2.7V to +5.5V, total CLAMP = 10nF, CCS = 3.3nF, tapped inductor = 2.3µH/115µH, 1:7 ratio (ISAT = 0.7A, RS = 1Ω),
TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C and VDD = 3.7V.) (Note 2)

Note 2: All parameters are 100% production tested at TA = +25°C and TA = +85°C, unless otherwise noted. Parameters at -40°C are
guaranteed by design.
Note 3: See the fSW Selection section when VBAT is above 5.5V.
