General Description
The YF3145 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 YF3145 is available in the SOT23-6L package and provides space-saving PCB for the
application fields.
