简介
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 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 internal soft-start and loop compensation circuit, it can be easily used with 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.
