RT8279 5A, 36V, 500kHz Step-Down Converter General Description Features The RT8279 is a step-down regulator with an internal power MOSFET. It achieves 5A of continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. z 5A Output Current z Internal Soft-Start 110mΩ Ω Internal Power MOSFET Switch Internal Compensation Minimizes External Parts Count High Efficiency up to 90% 25μ μA Shutdown Mode Fixed 500kHz Frequency Thermal Shutdown Cycle-by-Cycle Over Current Protection Wide 5.5V to 36V Operating Input Range Adjustable Output Voltage from 1.222V to 26V Available In an SOP8 (Exposed Pad) Package RoHS Compliant and Halogen Free For protection, the RT8279 provides cycle-by-cycle current limiting and thermal shutdown protection. An adjustable soft-start reduces the stress on the input source at startup. In shutdown mode, the regulator draws only 25μA of supply current. z z z z z z z z The RT8279 requires a minimum number of readily available external components, providing a compact solution. The RT8279 is available in the SOP-8 (Exposed Pad) package.
