Featuress
AEC-Q100 qualified
Two step-down synchronous switching
voltage regulators with internal power switches:
– Wide 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
Datasheet - production data
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
