® RT6158A High Efficiency, Low Quiescent, 2A Buck-Boost Converter General Description The RT6158A converter is a high efficiency single inductor converter which can operate with wide input voltage 2.5V to 5V such as battery which is higher or lower than the output voltage and it can supply the load current up to 2A. The maximum peak current in the switches is limited to a typical value of 4.5A. 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. The Buck-Boost operates at 2MHz typical switching frequency in full synchronous operation. The RT6158A operates in Pulse Frequency Modulation (PFM) mode for increasing efficiency.
