1. Current into supply pins without leakage of DCDC switches.
2. Limited by the 50mV output voltage accuracy for V REFIN < 0.84V
3. The dropout voltage is the input to output difference at which the output is 100mV below its nominal value.
System Characteristics
V IN1A = V IN1B = V IN2 = V PA_EN = V EN1 = V EN2 = 3.9V, T A = -40oC to +85oC. Typical values are at T A =+25oC, (unless
otherwise specified), for external components refer to Table 5 on page 7 . The following parameters are verified by
characterisation and are not production tested.
