Featuress

 AEC-Q100 qualified

 Two step-down synchronous switching voltage

regulators with internal power switches:

– W ide input voltage range (from 3.5 V to 26 V)

– Internal high-side/ low-side NDMOS

– 1 V minimum output

– 3.0 A load current

– 250 kHz free-run frequency

– 250 kHz < f < 2 MHz synchronization range

– Integrated soft-start

– Independent hardware enable pins

– Independent power supply

– 180° PWM output phase shift

– Programmable switching frequency divider

by 1, 2, 4 or 8 between the two DC/DC

regulators

– Power good function

 One standby / linear regulator

– Output voltage programmable with external

resistor divider

– 250 mA maximum current capability

– Backup function

– Power good function

 One high side driver

– 0.5 V max drop @ 0.5 A

– Protected against short to ground and

battery, loss of ground and battery,

unsupplied short to battery

 Programmable under voltage battery detector

– Under voltage threshold adjustable through

dedicated pin (VDIN)

 Load dump protection

 Independent thermal protection on all

regulators

 Independent current limit on all regulators

 Extremely low quiescent current in standby

conditions

 Power good / adjustable voltage detector

outputs to realize customized power up/down
