Description
The RAA211412 is a DC/DC step-down (Buck) regulator that supports a wide operating input voltage range (from 5.8V to 45V) and adjustable output voltage. It can deliver up to a continuous 1A output current with premium load regulation and line regulation performance. The RAA211412 employs the PWM peak-current mode control architecture at a 630kHz switching frequency and provides fast transient response performance. In addition, with an internal soft-start and loop compensation circuit, it can be easily used with the minimum BOM. The RAA211412 also offers protection features such as cycle-by-cycle current limit, input voltage UVLO, output voltage undervoltage protection, and thermal shutdown. The RAA211412 is available in the TSOT23-6 package.
