ELECTRICAL CHARACTERISTICS (continued) These specifications are written in the same style as common for standard
integrated circuits. The convention considers current flowing into the pin (sink current) as positive and current flowing out of the pin
(source current) as negative. (Conditions: VBAT = 4.0 V, VCC = 5.0 V nom, PWRON = VBAT , Operating Mode, −ICC = 10 mA, −25°C ≤ TA
≤ 85°C, L1 = 47 mH, RLIM = 0 W, CRDVCC capacitor = 10 mF, unless otherwise noted.)

4. See Figures 2 and 3.
5. The transistors T1 on lines IO, C4 and C8 (see Figure 24) have a max Rdson of 250 W.
6. Pin loading = 30 pF, except INVOUT = 15 pF.
7. As the clock buffer is optimized for low power consumption and hence not symmetrical, clock signal duty cycle is guaranteed for divide
by 2 and divide by 4 ratio.
8. In either direction.
