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.
