Description: The RAA211835 is a DC/DC asynchronous step-down (Buck) regulator that supports a 4.5V to 75V input voltage range and adjustable output voltage. It can deliver up to continuous 3A of continuous output current with premium load and line regulation performance.The RAA211835 uses peak-current mode control architecture. Its PWM switching frequency is programmable to provide the best trade-off between transient response and efficiency. It also supports PFM operation to maximize light load efficiency, in addition
