Note 1: Limits are 100% production tested at T A = +25°C for UCSP parts. Limits over the entire operating temperature range are
guaranteed by design and characterization but are not production tested.
Note 2: The minimum output voltage is the input voltage minus the forward voltage drop of the Schottky diode:
V OUT(MIN) = V V+ - V DIODE
Note 3: Specifications to -40°C are guaranteed by design and not production tested.
Typical Operating Characteristics
(See the Typical Applications Circuit , V V+ = V VP = 3.6V, I LED = 15mA, L1 = 22μH, C OUT1 = 0.1μF, C COMP = 0.022μF, R SENSE = 7.5 Ω ,
V CTRL = 1.5V, 4 LEDs, T A = +25°C, unless otherwise noted.)
