Renesas RAA230409

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)
• ¾ Synchronous rectification type step-down circuit
• ¾ Integrated power MOSFETs
• ¾ Internal phase compensator
• ¾ Power good function (ch1)
• ¾ Low power mode
• (ch1, ch3 and ch4 operate at low frequency and reduce the power consumption of the IC.)
• ¾ Switching frequency: 1.3 MHz to 2 MHz (variable)
• ¾ Internal timer-latch-type short-circuit protector
• • LDO (ch2)
• ¾ Internal over current protector (foldback-current limiting)
• • Common part
• ¾ Independent On/Off control for each channel
• ¾ Internal digital soft-start function (adjustable soft-start time)
• ¾ Internal discharge circuit
• ¾ Internal timer-latch-type thermal shutdown circuit (shutdown temperature: 150°C or higher)
• ¾ Internal recovery-type under voltage lockout circuit
