D. TPS563200
General Description
TPS563200 are simple, easy-to-use, 3 A synchronous step-down (buck) converters in SOT-23 package. The
devices are optimized to operate with minimum external component counts and also optimized to achieve low
standby current. These switch mode power supply (SMPS) devices employ D-CAP2 mode control providing a
fast transient response and supporting both low equivalent series resistance (ESR) output capacitors such as
specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components.
TPS563200 operate in Advanced Eco-mode, which maintains high efficiency during light load operation. The
devices are available in a 6-pin 1.6 x 2.9mm SOT (DDC) package, and specified from –40°C to 85°C of
ambient temperature.
