General Description

The RT6158H converter is a high efficiency single inductor converter which can operate with wide input voltage 2.5V to 5.5V such as battery which is higher or lower than the output voltage and it can supply the load current up to 3A.

The maximum peak current in the switches is limited to a typical value of 6.5A.

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.
