Description

The SCT12A2 is a high efficiency, fully integrated synchronous boost converter with a 13mΩ high-side MOSFET and a 11mΩ low-side MOSFET, supporting 2.7V to 20V input voltage range and up to 15-A switch current. The switch current limit can be adjusted with an external resistor. The device adapts 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. Using MODE pin sets either Pulse Frequency Modulation (PFM) operation or forced Pulse Width Modulation (PWM) operation. The SCT12A2 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 condition. The SCT12A2 monitors both output voltage and feedback voltage to protect over-voltage condition. It features cycle-by-cycle peak current limit and thermal shutdown protection when the device over loads current. SCT12A2 is available in a low-profile package DFN-20L 3.5mmx4.5mmx0.9mm with enhanced thermal power pad.
