FEATURES

● AEC-Q100 qualified
● Two step-down synchronous switching voltage regulators with internal power switches: – Output voltage selectable by external divider (feedback voltage at 0.9 V) – Minimum and maximum output is limited by minimum and maximum duty cycle – Internal high-side/ low-side NDMOS – 270 kHz and 2.2 MHz selectable free-run frequencies – 125 kHz < f < 2.3 MHz synchronization range at SYNCIN pin – Programmable current limits at 2 A and 4.5 A (> 2 A requires the addition of external schottky diodes) – Independent hardware enabling pins – Independent supply inputs – 180° phase shift between outputs – Synch out 90° phase shift vs DC-DC1 – Programmable switching frequency divider by 1, 2, 4, 8 between the two regulators
● Independent voltage supervisors/power-goods with selectable thresholds through external pin: – two available thresholds for UV/OV/PG signals: 90-120-95% or 80-110-85% (output voltage percentage)
● Soft-start, thermal protection
● One standby/linear regu...
