Low-Cost Multiple-Output
Power Supply for LCD TVs
ELECTRICAL CHARACTERISTICS (continued)
(Circuit of Figure 1, V IN = V IN2 = 12V, AV DD = V OVIN = V SUP = 15V, T A = -40°C to +85°C . Typical values are at T A = +25°C, unless
otherwise noted.) (Note 4)

Note 2: When the inductor is in continuous conduction (EN2 = VL or heavy load), the output voltage has a DC regulation level lower than
the error comparator threshold by 50% of the output voltage ripple. In discontinuous conduction (EN2 = GND with light load), the
output voltage has a DC regulation level higher than the error comparator threshold by 50% of the output voltage ripple.
Note 3: Disables boost switching if either SUP, SWI, or OVIN exceeds the threshold. Switching resumes when no threshold is exceeded.
Note 4: Specifications to -40°C are guaranteed by design, not production tested.
Typical Operating Characteristics
(Circuit of Figure 1. V IN = V INL = V SUP = 12V, AV DD = 16V, V GON = 34.5V, V GOFF = -6V, V OUT1 = 3.3V, T A = +25°C, unless other-
wise noted.)
