The SCT1270Q is a high efficiency synchronous boost converter with fully integrated a 17mΩ highside MOSFET and a 14mΩ low-side MOSFET, featuring 2.75V to 12V input voltage range to support single cell or two cell Lithium-ion/polymer batteries and up to 9.5A peak switch current. The switch current limit can be adjustable with an external resistor. The SCT1270Q has 7A continuous switch current capability and provides output voltage up to 12V. The SCT1270Q adopts constant off-time peak current control to provide fast transient response. An external compensation network allows flexibility setting loop dynamics to achieve optimal transient performance at different load conditions. The SCT1270Q works in the PWM at moderate and heavy load condition. The SCT1270Q offers PFM mode at light load condition. The switching frequency is adjustable from 200kHz to 600kHz. The SCT1270Q features output overvoltage protection and thermal shutdown protection when the device overloads.

The device is available in a FCQFN-11L 2.5mm x2mm package.
