FP6291 is a current mode step-up DC-DC converter . Its PWM circuit with built-in 0.2Ω power MOSFET makes this regulator highly efficient. Internal compensation network also minimizes external component count up to 6. The non-inverting input of the error amplifier is connected to a 0.6V precision reference voltage and the internal soft-start function can reduce the inrush current. FP6291 is available in SOT23-6L package and provides space-saving PCB for application fields .
