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
