See the Application Information section of this data sheet for more details.

(2)

See the Application Information section of this data sheet for more details.

(3)

Up to 2 mA can flow into VCC when both converters are running in PWM, this resistor causes the UVLO threshold to be shifted

accordingly.

CC = VINDCDC1/2 = 3.6 V, EN = VCC, MODE = GND, L = 2.2 µH, CO = 10 µF. TA = -40°C to 85°C, typical values are at

A = 25°C (unless otherwise noted).
