General Description

The RTQ1741A is a high efficiency single inductor BuckBoost Converter which can operate with wide input voltage such as battery which is higher or lower than the output voltage and it can supply the load current up to 4A.

The maximum peak current in the switches is limited to a typical value of 4.5A.

The RTQ1741A feedback loop is internally compensated for both Buck and Boost operation and it provides seamless transition between Buck and Boost modes and optimal transient response.
