FUXIN 原装正品 FT8891 封装SOT23-6 恒流模式升压IC FT8891General Deion The FT8891 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.25Ω power MOSFET make this regulator highly power efficient. The internal compensation network also minimizes as much as 6 external component counts. The non-inverting input of error amplifier connects to a 0.6V precision reference voltage and internal soft-start function can reduce the inrush current. The FT8891 is available in the SOT23-6L package and provides space-saving PCB for the application fields. FT8891 Features: -Adjustable Output up to 24V -Internal Fixed PWM frequency: 1.0MHz -Precision Feedback Reference Voltage: 0.6V (±2%) -Internal 0.25Ω, 2A, 26V Power MOSFET -Shutdown Current: 0.1μA - Over Voltage Protection -Over Temperature Protection -Adjustable Over Current Protection: 0.5A ~ 2.5A -Package: SOT23-6L Applications: - Chargers - LCD Displays - Digital Cameras - Handheld Devices - Portable Products
