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
sequences
