Note 1: All devices are 100% tested at T A = +25°C. All limits over the temperature range are guaranteed by design.
Note 2: The MAX1605 requires a supply voltage between +2.4V and +5.5V; however, the input voltage used to power the inductor
can vary from +0.8V to V OUT .
Typical Operating Characteristics
(V CC = 3.3V, V IN = 3.6V, L1 = 10μH, SHDN = LIM = V CC , V OUT(NOM) = 18V (Figure 3), T A = +25°C, unless otherwise noted.)
