Texas Instruments TPS563212 Synchronous Buck Converter is a cost-effective and highly flexible synchronous buck converter that provides selectable Eco-mode operation or FCCM (force continuous conduction mode) operation. A selectable power-good indicator or external soft-start is also configurable through the MODE pin. Power sequencing is possible by configuring the Enable pin, power-good indicator, or external soft start. A wide input voltage range of 4.2V to 18V supports many common input rails like 12V and 15V. It supports up to 3A continuous output current at output voltages between 0.6V and 7V.
The device provides a fast transient response with true fixed switching frequency through the Advanced Emulated Current Mode (AECM) control topology. With internal smart loop bandwidth control, the device provides a fast transient response over a wide output voltage range without the need for external compensation.
Cycle-by-cycle current limit on the high-side peak current protects the device in overload situations. It is enhanced by a low-side valley current limit, which prevents current runaway. Hiccup mode would be triggered by under-overvoltage protection (OVP), undervoltage protection (UVP), UVLO protection, and thermal shutdown. The Texas Instruments TPS563212 is available in a 1.6mm × 2.1mm SOT5X3 package.
