AF6291
AF6291 is current mode boost DC-DC converter manufactured by AFSEMI.
Description
The AF6291 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 pensation network also minimizes as much as 6 external ponent 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 AF6291 is available in the SOT23 -6L package and provides space-saving PCB for the application fields.
