7. Efficiency is defined by 100 * (Pout / Pin) at 25°C
VIN = 4.2 V with L= Coilcraft DT1608C−223
IOUT = 30 mA, Load = 5 LEDs (VF = 3.5 V per LED) bypassed by 1 mF X5R
8. Guaranteed by design and characterized with L = 22 mH, DCR = 0.7 W max.
9. Load = 4 LEDs (VF = 3.5 V by LED), COUT = 1 mF X5R, L= Coilcraft DT1608C−223.
10. VIN = 3.6 V, Ripple = 0.2 V P−P, IOUT = 15 mA.
