General Description
The SL1573 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.2Ω powerMOSFET make this regulator highly power efficient. The internal compensation network also minimizesas much as 6 external component counts. The non-inverting input of error amplifier connects to a 0.6Vprecision reference voltage and internal soft-start function can reduce the inrush current.
The SL1573 is available in the SOT23-6L package and provides space-saving PCB for theapplication fields.
