TYPICAL CHARACTERISTICS

VIN = VEN = 3.3V, VOUT = 9V, L = 1.5μH, TA = 25°C, unless otherwise noted.

NOTE:

13) When VIN is higher than 3.4V, VIN supplies power to VDD, so the IQ on VIN rises higher when VIN > 3.4V. When VIN is 3V, the higher

voltage source of either VIN or VOUT supplies VDD, so the IQ on VOUT rises higher when VOUT > 3V and VIN = 3V.
