RT6158HWSC Product Details

The RT6158HWSC 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. The Buck-Boost operates at 2MHz typical switching frequency in full synchronous operation. The RT6158HWSC operates in Pulse Frequency Modulation (PFM) mode for increasing efficiency. The PFM mode can be disabled, forcing the RT6158HWSC to operate at a fixed switching frequency operation at 2MHz. The RT6158HWSC can also be synchronized with external frequency at MODE pin from 2.2MHz to 2.6MHz. The RT6158HWSC output voltage is programmable using an external resistor divider; the output voltage range is from 2.1V to 5.2V.
