FEATURES AND BENEFITS
• Automotive AEC-Q100 qualified
• Input operating voltage range: 3.5 to 36 V
□ Withstands surge voltages to 40 V for load dump
• Low-Power (LP) mode—draws just 8 µA from VIN while
maintaining 3.3 or 5.0 VOUT
• AUTO mode allows automatic transition between PWM
and LP mode based on load current
• Programmable PWM frequency (fSW): 250 kHz to 2.4 MHz
• PWM frequency dithering and controlled switch node
slew rate reduce EMI/EMC signature
• CLKOUT allows interleaving and dithering of “downstream”
regulators using their synchronization inputs
• Interleaving minimizes input filter capacitor requirement
and improves EMI/EMC performance
• Synchronization of PWM frequency to external clock on
SYNCIN pin
• Adjustable output voltage: ±1.5% accuracy over
operating temperature range (‒40°C to 150°C)
• Maximized duty cycle at low VIN improves dropout
• Soft recovery from dropout condition
• Adjustable soft-start time controls inrush current to
accommodate a wide range of output capacitances
• External compensation provides flexibility to tune the
system for maximum stability or fast transient response
• Enable input can command ultralow 1 µA shutdown current
• Open-drain PGOOD output with rising delay
• Pre-bias startup allows quick restart and avoids reset
• Overvoltage, pulse-by-pulse current limit, hiccup mode short
circuit, and thermal protections
• Robust FMEA: pin open/short and component faults
