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
