Fixed 5V, 500mA, 2.2 MHz Step-Down Converter with low quiescent current and integrated powertransistor

Features

  • 500 mA step down voltage regulator
  • 5 V Output voltage
  • ± 2% output voltage tolerance
  • Low quiescent current (less than 45μA at nominal input voltage)
  • Integrated power transistor
  • Current mode PWM regulation
  • PFM mode for light load current
  • Input voltage range from 4.75V to 45V
  • 2.2 MHz switching frequency
  • 100% Duty cycle
  • Synchronization input
  • Very low shutdown current consumption (<2 μA)
  • Soft-start function
  • Input under voltage lockout
  • Suited for industrial applications: Tj = -40 °C to +125 °C
  • Green Product (RoHS compliant

Benefits

  • High switching frequency of 2.2MHz allows use of small inductors and capacitors henceminimizing board space required
  • Low quiescent current in shutdown makes the device suitable for battery powered systems
  • Pulse Frequency Modulation to optimize efficiency in light load conditions
