Datasheet Summary
4.5V to 42V, 5A, DC/DC Synchronous Step-Down Regulator w/ Internal pensation and Adjustable Frequency
The RAA211450 is a DC/DC synchronous step-down (Buck) regulator that supports a 4.5V to 42V input voltage range and adjustable output voltage. It can deliver up to continuous 5A of continuous output current with premium load and line regulation performance.
The RAA211450 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...
