General Description
The RZC6291 is a current mode boost DC-DC converter. Its PWM circuitry with built-in
0.2Ω power MOSFET make this regulator highly power efficient. The internal compensat-
ion 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 RZC6291 is available in the SOT23-6L package and provides space-saving PCB for
the application fields.
