The SCT1270 is a high efficiency synonous boost converter with fully integrated a 17mΩ high-side MOSFET a 14mΩ low-side MOSFET, featuring 2.7V to 12V input voltage range to support single cell or two cell Lithium ion/polymer batteries up to 9.5A peak switch current. The switch current limit can be adjustable with an external resistor. The SCT1270 has 7A continuous switch current capability provides output voltage up to 12.6V.The SCT1270 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 SCT1270 works in the PWM at moderate heavy load condition. The SCT1270 offers PFM mode at light load condition. The switching frequency is adjustable from 200KHz to 2.2MHz.The SCT1270 features output overvoltage protection thermal shutdown protection when the device over loads.The device is available in a QFN-11 2mm x 2.5mm package.
