General Description

The SL1573 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.2 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 SL1573 is available in the SOT23-6L package and provides space-saving PCB for the

application fields.
