Description
The RAA23021x is a high efficiency monolithic step-down DC/DC synchronous converter plus a LDO (low dropout)
regulator which has an ultra-low power mode.
Features
• DC/DC converter (ch1)
⎯ Synchronous rectification type step-down circuit
⎯ Integrated power MOSFETs
⎯ Preset output voltage (There are also products that have adjustable output voltage using external resistors.)
⎯ Internal phase compensator
⎯ Switching frequency: 1 MHz (fixed)
⎯ Internal timer-latch-type short-circuit protector (fixed delay time)
⎯ 100% duty cycle operation
• LDO (ch2)
⎯ 500mA
⎯ Internal over current protector (foldback-current limiting)
⎯ Ultra low-power save mode (25uA typical)
• Common Features
⎯ Internal rise up sequencer
⎯ Internal digital soft-start function (2 ms fixed soft-start time)
⎯ Internal discharge circuit
⎯ Power good function
⎯ Internal timer-latch-type thermal shutdown circuit (shutdown temperature: 150°C or higher)
⎯ Internal recovery-type under voltage lockout circuit
Application
⎯ Communication
⎯ Industrial
⎯ Building
⎯ Smart meter
And, usable around MCU, ASIC, FPGA, etc.
