Silicontent Technology SCT12A3

Beschreibung

The SCT12A3 is a high efficiency synchronous boostconverter with fully integrated a 13mΩ high-sideMOSFET and an 11mΩ low-side MOSFET, supporting 2.7V to 20V input voltage range and up to 15-A switch current. The input switch current limit can be adjustable with an external resistor.The SCT12A3 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 SCT12A3 features two-level Adjustable AdaptiveOutput (AAO). The SCT12A3 delivers much higher power to satisfy the instant big output power demanding by boosting the output to the higher programmed voltage level.The SCT12A3 offers the gate control for an external P-channel MOSFET to disconnect load from boost converter output. The safety feature prevents the damage on load from input shooting through to output in shutdown condition. It features 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.
