Top Features
- Automotive AEC-Q100 qualified
- Withstands surge voltages up to 40 V
- Operates as low as 3.4 VIN (typ) with VIN decreasing
- Utilizes pulse frequency modulation (PFM) to draw only tens of microamperes from VIN while maintaining keep-alive VOUT
- PWM/PFM mode control input pin
- Delivers up to 3.0 A of output current with integrated 110 mΩ high voltage MOSFET
- SLEEP input pin commands ultra-low current shutdown mode
- Adjustable output voltage with ±1.0% accuracy from 0°C to 85°C, ±1.5% from –0°C to 150°C
- Programmable switching frequency: 250 kHz to 2.4 MHz
- Synchronization capability: applying a clock input to the PWM/PFM input pin will increase the PWM frequency
- Active low, power-on reset (NPOR) open-drain output
- Maximized duty cycle for low dropout
- Enhanced recovery Idle-Stop Transients
- Pre-bias startup capable, VOUT will not cause a reset
- External compensation for maximum flexibility
- Stable with ceramic or electrolytic output capacitors
- Excellent set of protection features to satisfy the most demanding applications
- Overvoltage, pulse-by-pulse current limit, hiccup mode short circuit, and thermal protection
- Robust FMEA, with pin open/short and component faults
- Thermally enhanced, surface mount package
