Description: Constant On-Time Buck Regulator

Features

* AEC-Q100 Grade 0 qualified
* Internal buck pre-regulator followed by LDO outputs
* 5.5 to 36 V VIN operating range (50 V maximum); for start/stop, cold crank, and load dump requirements
* 2.2 MHz constant on-time buck regulator
* 50 V absolute maximum input

Applications

* Efficient operation is achieved by using a buck pre-regulator to efficiently drop the input voltage before supplying the linear regulators; this reduces power dissipation and increases overall regulator efficiency. The switching regulator is capable of operating at a nominal switching frequency of
