Jeking Daily Post: FP6276B

#Synchronous, #Boost, #Converter, #Efficient, #Compact **FP6276B: A High-Efficiency Synchronous Boost Converter** **Product Overview** The FP6276B is a high-performance, current-mode synchronous DC-DC boost converter designed for portable applications requiring efficient power conversion. Manufactured by Feeltrend (Far Eastern Horizon), this compact IC integrates both a 40mΩ high-side and low-side MOSFET, enabling high efficiency up to 93% in a small footprint. It operates within an input voltage range of 2.4V to 4.5V, making it ideal for single-cell lithium-ion battery-powered devices. With a fixed switching frequency of 500kHz and internal compensation, the FP6276B simplifies circuit design by minimizing external components to just six. **Key Features** This chip features PWM/PSM control for optimal efficiency across light and heavy loads. It provides a precise 0.6V feedback reference voltage (±2%) and supports adjustable output voltages up to 5.3V, commonly set at 5V for USB-compatible applications. The FP6276B includes comprehensive protection mechanisms such as over-current protection (OCP), over-temperature protection (OTP), and output over-voltage protection (OVP). Its ultra-low quiescent current (<0.1μA) and enable (EN) pin with shutdown functionality allow for complete output disconnection, significantly reducing standby power consumption. **Main Applications** The FP6276B is widely used in portable electronics such as power banks, Bluetooth speakers, KTV gadgets (K-singing boxes), beauty devices, and e-cigarettes. Its high efficiency, compact SOP-8L (EP) package, and robust protection features make it a reliable choice for consumer-grade mobile products. **Recommended by Jeking Electronic Limited** Jeking Electronic Limited, a trusted supplier of semiconductor solutions based in Shenzhen, highly recommends the FP6276B for cost-sensitive, high-efficiency designs.
