RAA230403 - 3-ch Step-Down Switching Regulator + 1-ch LDO

Download the RAA230403 datasheet PDF. This datasheet also covers the RAA230401 variant, as both devices belong to the same 3-ch step-down switching regulator + 1-ch ldo family and are provided as variant models within a single manufacturer datasheet.

Description

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

Features

  • Switching Regulator (ch1, ch3, ch4)  Synchronous rectification type step-down circuit  Integrated power MOSFETs  Internal phase compensator  Power good function (ch1)  Low power mode (ch1, ch3 and ch4 operate at low frequency and reduce the power consumption of the IC. )  Switching frequency: 1.3 MHz to 2 MHz (variable)  Internal timer-latch-type short-circuit protector.
  • LDO (ch2)  Internal over current protector (foldback-current limiting).
  • Common part  Indep.
