供应AL680,AL681,AL682,AL683,AL684,AL685,AL686,AL687,AL688,AL689恒流模式PWM升压IC

The SD6271 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 SD6271 is available in the SOT23-6L package and provides space-saving PCB for the application fields.
