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...
