Note 1: 3.3 k resistive load, 3.3VOUT (1 mA).
2: For VIN > VOUT, VOUT will not remain in regulation.
3: IQ is measured from VOUT; VIN quiescent current will vary with boost ratio. VIN quiescent current can be
estimated by: (IQPFM * (VOUT/VIN)), (IQPWM * (VOUT/VIN)).
4: Peak current limit determined by characterization, not production tested
5: 220 resistive load, 3.3VOUT (15 mA).
