The RT9270 is a high performance, low noise, fixedfrequency step up DC-DC Converter. The RT9270converters input voltage ranging 2.3V to 5.5V into outputvoltage up to 14V. Current mode control with externalcompensaTIon network makes it easy to stabilize thesystem and keep maximum flexibility. Programmable softstart funcTIon minimizes impact on the input power system.Internal power MOSFET with very low RDS(ON) provideshigh efficiency. The RT9270 automaTIcally transits fromPWM to PSM (Pulse Skipping Mode) during light loadcondiTIon further increasing efficiency. 670kHz and1.3MHz operation frequency options provide flexibiltity ofminimum output filter size, maximum efficiency and lowBOM cost.The RT9270 also provides comprehensive protectionfunctions such as UVLO, OCP, OTP, OVP and short circuitprotection.
