Description
Wide Input Voltage, 2 A Buck Regulator Family with Low IQ Mode, it is 5V, PWM/ PFM mode
Features
Automotive AEC-Q100 qualifiedWithstands surge input to 40 VIN for load dumpOperates down to 3.4 VIN (typ), 3.6 VIN (max) for idle stopUtilizes pulse frequency modulation (PFM) for low IQ modeFunction options: Selectable PWM / Low IQ PFM mode, orSelectable 10 μA Sleep mode (automatic PWM / Low IQ PFM mode selection)
Fixed output voltage options: 3.3 V or 5 V with ±1.0% accuracyDelivers up to 2 A of output currentIntegrated 110 mΩ high-side MOSFETAdjustable switching frequency from 300 to 550 kHz (to 605 kHz with sync)EMI Reduction Features: Frequency ditheringControlled switching node
External synchronization capabilityActive low NPOR output with 7.5 ms delayPre-bias startup capable: VOUT increases monotonically, will not cause a resetExternal compensation for maximum flexibilityStable with ceramic or electrolytic output capacitorsInternally fixed soft start time of 5 msPulse-by-pulse current limit, hiccup mode short circuit, and thermal protectionsPin open/short and component fault tolerant
