Renesas RAA230214

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

Typical applications

• Communication
• Building
• Smart meter
• Industrial
