The FP6291 is a boost converter of current mode , PWM circuitry with a built-in 0.13Ω 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 1.238V 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 FP6291 is available in the MSOP-8L package, using of low ESR capacitors and reduced PCB space for the step-up application fields.
