The RT9270 is a high performance, low noise, fixed
frequency step up DC-DC Converter. The RT9270
converters input voltage ranging 2.3V to 5.5V into output
voltage up to 14V. Current mode control with external
compensation network makes it easy to stabilize the
system and keep maximum flexibility. Programmable soft
start function minimizes impact on the input power system.
Internal power MOSFET with very low RDS(ON) provides
high efficiency. The RT9270 automatically transits from
PWM to PSM (Pulse Skipping Mode) during light load
condition further increasing efficiency. 670kHz and
1.3MHz operation frequency options provide flexibiltity of
minimum output filter size, maximum efficiency and low
BOM cost.
The RT9270 also provides comprehensive protection
functions such as UVLO, OCP, OTP, OVP and short circuit
protection.
