description (continued)
Output 1 (OUT1) can deliver a maximum of 40 mA, from a 1-V input, with output 2 (OUT2) not loaded. OUT2
can deliver a maximum of 20 mA, from a 1-V input, with OUT1 not loaded. Both outputs can be loaded in the
same time, but the total output current of the first voltage doubler must not exceed 40 mA. For example, the load
at OUT1 is 20 mA and the load at output 2 is 10 mA.
The devices operate in the newly developed LinSkip mode. In this operating mode, the device switches
seamlessly from the power saving, pulse-skip mode at light loads, to the low-noise, constant-frequency
linear-regulation mode, once the output current exceeds the device-specific output current threshold.
A power-good function supervises the output voltage of OUT2 and can be used for power up and power down
sequencing. Power good (PG) is offered as either open-drain or push-pull output.
