A high switching frequency of typically 2.
5 MHz allows the use of small inductors and provides fast transient response as well as high output-voltage accuracy by the use of DCS-Control topology.
With their wide operating input-voltage range of 3 V to 17 V, the devices are ideally suited for systems powered from either Li-Ion or other batteries as well as from 12-V intermediate power rails.
The devices support up to 1-A continuous output current at output voltages between 0.
9 V and 6 V (in 100% duty-cycle mode).
The soft-start pin controls the output-voltage start-up ramp, which allows operation as either a standalone power supply or in tracking configurations.
Power sequencing is also possible by configuring the enable (EN) and open-drain power-good (PG) pins.
