3.3 K Ω resistive load, 3.3V OUT (1 mA).
For V IN > V OUT , V OUT will not remain in regulation.
I Q is measured from V OUT ; V IN quiescent current will vary with boost ratio. V IN quiescent current can be
estimated by: (I QPFM * (V OUT /V IN )), (I QPWM * (V OUT /V IN )).
220 Ω resistive load, 3.3V OUT (15 mA).
Peak current limit determined by characterization, not production tested.
