RT9277C/RT9277D

High Performance, Low Noise Boost Converter

RT9277C/RT9277D
New

The RT9277C/D is a high performance, low noise, fixed frequency step up DC-DC Converter. The RT9277C/D converters input voltage ranging 2.5V to 5.5V into output voltage up to 16V. Current mode control with external compensation network makes it easy to stabilize the system and keep maximum flexibility. Soft start function minimizes impact on the input power system. Internal power MOSFET with very low RDS(ON) provides high efficiency. The RT9277C/D with 640kHz and 1.2MHz operation frequency options provide flexibiltity of minimum output inductor size, maximum efficiency and low BOM cost.
The RT9277C/D also provides comprehensive protection functions such as UVLO, OCP and OTP.
