Overview
Description
The RAA211605 is a DC/DC step-down buck regulator that supports a wide operating input voltage range (from 4.5V to 60V) and adjustable output voltage. It can deliver up to continuous 0.5A output current with excellent load regulation and line regulation performance.
The RAA211605 employs peak-current mode control with a 450kHz nominal switching frequency and pulse skipping mode under light load. It provides fast and robust transient response performance. Internally implemented soft-start and loop compensation circuitry also help to simplify design and minimize BOM cost.
The RAA211605 also offers protection features such as cycle-by-cycle current limit, input voltage UVLO, output voltage undervoltage protection, and thermal shutdown.
The RAA212605 is available in the TSOT23-6 package.
