Datasheet RAA211820 4.5V to 75V, 2A, DC/DC Synchronous Step-Down Regulator w/ Internal Compensation and Adjustable Frequency The RAA211820 is a DC/DC synchronous step-down (Buck) regulator that supports a 4.5V to 75V input voltage range and adjustable output voltage. It can deliver up to continuous 2A of continuous output current with premium load and line regulation performance. The RAA211820 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 and DEM to maximize light load efficiency, in addition to an external bias LDO input to further reduce power dissipation across the load range.
