高效率低纹波升压转换器RT9270
RT9270 high performance, noise, fixed frequency step DC-DC Converter. RT9270 converters input voltage ranging 2.3V 5.5V into output voltage 14V. Current mode control with external compensation network makes easy stabilize system keep maximum flexibility. Programmable soft start function minimizes impact input power system. Internal power MOSFET with very RDS(ON) provides high efficiency. RT9270 automatically transits from (Pulse Skipping Mode) during light load condition further increasing efficiency. 670kHz 1.3MHz operation frequency options provide flexibiltity minimum output filter size, maximum efficiency cost. RT9270 also provides comprehensive protection functions such UVLO, OCP, OTP, short circuit protection.
