Key features
  • AEC-Q100 qualified
  • Two step-down synchronous switching voltage regulators with internal power switches:
    • Wide operating input voltage range (from 3.3 V to 26 V)
    • Output voltage selectable by external divider (feedback voltage at 0.9 V)
    • 0.9 V minimum output, maximum output limited by maximum Duty Cycle
    • DC/DCs can work in Low Power Mode for reduced current consumption in low output Load
    • Internal high-side/ low-side NDMOS
    • 250 kHz and 2 MHz selectable free-run frequencies
    • 250 kHz < f < 2.3 MHz synchronization range at SYNCIN pin
    • Programmable current limits at 2 A and 4 A
    • Independent hardware high voltage enabling pins
    • Independent supply inputs
    • 180° phase shift, synch out is 90° out of phase with DC/DC1
    • Programmable switching frequency divider by 1, 2, 4, 8 between the two regulators
    • The two regulators can be paralleled
  • 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 regulator:
    • Output selectable with external resistor divider till 10 V
    • Soft start, hardware enable pin
    • 250 mA maximum current capability
    • Standby operative mode
    • Programmable power good thresholds (85% or 95% output voltage percentage)
    • Thermal protection
  • Microcontroller reset with programmable duration, activated by output under voltage or watchdog fault
  • External High Side Driver enable pin
  • One integrated window watchdog (5 ms ≤ window ≤ 50 ms, with ± 20% tolerance)
  • Short circuit protected outputs
  • Low external components number
  • Low EMI
  • Automotive qualified - AECQ 100 (-40 to 105°C)
  • Thermal shutdown junction temperature 150°C
