RT9276GQW RT9276G EW= Marking EW= IC

The RT9276 Charging IC is a high-efficiency step-up (boost) DC-DC converter designed for portable and battery-powered devices. It allows flexible output voltage configuration through an external resistor divider or by using a fixed output setting. The converter features a shutdown mode that completely disconnects the load from the battery, minimizing standby power consumption.

With a peak switch current limit of 2A, the RT9276 ensures stable operation under various load conditions. It also includes a low-EMI mode to reduce inductor ringing in discontinuous conduction, improving system noise performance. Additionally, an integrated voltage detector provides accurate low-battery detection, making it ideal for compact mobile systems.
