RT2101A
RT2101A is Synchronous Step-Down Converter manufactured by Richtek.
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. The over-temperature threshold is 145°C.
The RT2101A is available in WQFN-16L 3x3 package.
