R18DS0004EJ0102 Rev.1.02 Jul.09, 2013 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 (c.
• 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 Independent On/Off control for each channel Internal digital soft-start function (adjustable soft-start time) Internal discha.
