RT6158H

The RT6158H converter is a high efficiency single inductor 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 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 1.5MHz typical switching frequency in full synchronous operation. The RT6158H operates in Pulse Frequency Modulation (PFM) mode for increasing efficiency during low power RF transmission modes. The PFM mode can be disabled, forcing the RT6158H to operate at a fixed switching frequency operation at 2MHz. The RT6158H can also be synchronized with external frequency from 2.2MHz to 2.6MHz. The RT6158H output voltage is programmable using an external resistor divider; the output voltage range is from 2.1V to 5.2V.资料下载
