Reference Design Sample & Design Tools Buy ® RT2101A 2.95V to 6V Input, 3A Output, 2MHz, Synchronous Step-Down Converter General Description The RT2101A is a high efficiency step-down converter and capable of delivering 3A output current over a wide input voltage range from 2.95V to 6V. The RT2101A provides accurate regulation for a variety of loads with ±2.5% accuracy. For reducing inductor size, it provides up to 2MHz switching frequency. The efficiency is maximized through the integrated 45mΩ MOSFETs and 550μA typical supply current. Under-voltage lockout voltage of the RT2101A is 2.7V, and it also provides external setting by a resistor network on the enable pin. The RT2101A provides protections such as inductor current limit under-voltage lockout and thermal shutdown.
