DESCRIPTION
The SCT12A2 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 20V input voltage range and up to
15-A switch current. The switch current limit can be
adjustable with an external resistor.
The SCT12A2 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. Connection MODE pin to
ground selects the Pulse Frequency Modulation
(PFM) 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.
The device is available in a low-profile package DFN20L 3.5mmx4.5mmx0.9mm with enhanced thermal
power pad.
