DESCRIPTION：

 

The SCT12A1 is a high efficiency synchronous boost converter with fully integrated a 13mΩ high-side MOSFET and an 11mΩ low-side MOSFET, supporting 2.7V to 14V input voltage range and up to 12-A switch current. The switch current limit can be 
adjustable with an external resistor. 
The SCT12A1 adapts constant off-time peak current control to provide fast transient. An external compensation network allows flexibility setting loop dynamics to achieve optimal transient performance at different load conditions. Using MODE pin selects 
either Pulse Frequency Modulation (PFM) operation or forced Pulse Width Modulation (PWM) operation.
The SCT12A1 offers the gate control for an external P-channel MOSFET to disconnect load from boost converter output. This safety feature prevents the damage on load from input shooting through to output in shutdown or output hard short to ground condition.
The SCT12A1 monitors both output voltage and feedback voltage to protect overvoltage condition. It features cycle-by-cycle peak current limit and thermal shutdown protection when the device over loads.
The device is available in a low-profile package DFN-20L 3.5mmx4.5mmx0.9mm with enhanced thermal power pad.
