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
 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
