Beschreibung

The RAA23040x is a power supply IC that has 3-ch step-down Switching Regulator containing power MOSFETs and 1-ch LDO.

Eigenschaften

  • Switching Regulator (ch1, ch3, ch4)
  • ¾ Synchronous rectification type step-down circuit
  • ¾ Integrated power MOSFETs
  • ¾ Internal phase compensator
  • ¾ Power good function (ch1)
  • ¾ Low power mode
  • (ch1, ch3 and ch4 operate at low frequency and reduce the power consumption of the IC.)
  • ¾ Switching frequency: 1.3 MHz to 2 MHz (variable)
  • ¾ Internal timer-latch-type short-circuit protector
    • LDO (ch2)
  • ¾ Internal over current protector (foldback-current limiting)
    • Common part
  • ¾ Independent On/Off control for each channel
  • ¾ Internal digital soft-start function (adjustable soft-start time)
  • ¾ Internal discharge circuit
  • ¾ Internal timer-latch-type thermal shutdown circuit (shutdown temperature: 150°C or higher)
  • ¾ Internal recovery-type under voltage lockout circuit
