SP6660 Datasheet, PDF (7/22 Pages) Sipex Corporation – 200mA Charge Pump Inverter or Doubler

TYPICAL PERFORMANCE CHARACTERISTICS
V_IN = +3.6V, T_AMB = 25^oC unless otherwise noted. LF = Low Frequency, FC = Open, C1 = C2 = 150µF.
HF = High Frequency, FC = V+, C1 = C2 = 22µF. Inverter Circuit use Figure 1. Doubler Circuit use Figure 2.
