FP6290 Low-Noise Step-Up Current Mode PWM IC 2020年10月停产 General Description Download     The FP6290 is a boost converter of current mode , PWM circuitry with a built-in 0.2Ω power MOSFET provides a highly efficient regulator. Selectable high switching frequency allows easy filtering, faster loop performance in a low noise output. The non-inverting input of error amplifier connects to a 1.24V precision reference voltage. Soft-Start is programmed with an external capacitor, which sets the input current ramp rate. Current mode control and external compensation network make it easy and flexible to stabilize the system. The FP6290 is available in the MSOP-8L package, using of low ESR capacitors and reduced PCB space for the step-up application fields. ˙Data Sheet ˙Application Note ˙LCM Application Note Features ˙Precision feedback reference voltage: 1.24V  ˙Current Limit Protection  ˙Internal fixed PWM frequency ˙Pin control frequency: 640KHz/1.2MHz ˙External Programmable Soft-Start function (SS) ˙Internal 0.2Ω, 1.6A, 14V Power MOSFET ˙Shutdown Current : 0.1uA ˙Adjustable Output from VCC to 12V ˙Package: MSOP8
