Texas Instruments TPS563211 3A Synchronous Buck Converter is a flexible, cost-effective solution in a SOT583 package. The TPS563211 Converter features a selectable Eco-mode operation or FCCM (Force Continuous Conduction Mode) operation. Furthermore, a selectable Power-Good indicator or external soft-start is also configurable through the MODE pin. The TPS563211 allows power sequencing by configuring Enable, Power-Good indicator, or external soft-start correctly. A 4.2V to 18V wide input voltage range supports a wide variety of common input rails, such as 12V and 15V. The device supports up to 3A continuous output current at output voltages between 0.6V and 7V.
The TI TPS563211 3A Synchronous Buck Converter implements a fast transient response with true fixed switching frequency using the Advanced Emulated Current Mode (AECM) control topology. Facilitating an internal smart loop bandwidth control, the TPS563211 provides a fast transient response over a wide output voltage range without the need for external compensation.
A cycle-by-cycle current limit on the high-side peak current protects the converter in overload situations. This feature is enhanced by a low-side valley current limit, which prevents current runaway. Hiccup mode is triggered under overvoltage protection (OVP), undervoltage protection (UVP), UVLO protection, and thermal shutdown.
The TPS563211 3A Synchronous Buck Converter is housed in a 1.6mm × 2.1mm SOT583 package.
