Overview
RT9277C/D High Performance, Low Noise Boost Converter General Description Features 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.
