Overview
The TPS562209DDCR is a 2-A synchronous step-down converter produced by Texas Instruments. This device is part of the TPS562209 and TPS563209 series, which are designed to be simple and easy to use. The TPS562209 is optimized to operate with a minimum number of external components and achieves low standby current. It employs the proprietary D-CAP2™ mode control, which provides a fast transient response and supports low equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors without the need for external compensation components.
