Beschreibung

The RAA23021x is a high efficiency monolithic step-down DC/DC synchronous converter plus a LDO (low dropout) regulator which has an ultra-low power mode.

Eigenschaften

  • DC/DC converter (ch1)
  • Synchronous rectification type step-down circuit
  • Integrated power MOSFETs
  • Preset output voltage (There are also products that have adjustable output voltage using external resistors.)
  • Internal phase compensator
  • Switching frequency: 1 MHz (fixed)
  • Internal timer-latch-type short-circuit protector (fixed delay time)
  • 100% duty cycle operation
  • LDO (ch2)
  • 500mA
  • Internal over current protector (foldback-current limiting)
  • Ultra low-power save mode (25uA typical)
  • Common Features
  • Internal rise up sequencer
  • Internal digital soft-start function (2 ms fixed soft-start time)
  • Internal discharge circuit
  • Power good function
  • Internal timer-latch-type thermal shutdown circuit (shutdown temperature: 150°C or higher)
  • Internal recovery-type under voltage lockout circuit

Typische Anwendungen

  • Industrial
  • Smart meter
  • Building
