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 (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 discharge circuit  Internal timer-latch-type thermal shutdown circuit (shutdown temperature: 150°C or higher)  Internal recovery-type under voltage lockout circuit PKG and Packing Part No.
