TPS562209DDCT

The TPS562209DDCT is a simple, easy-to-use 2A Synchronous Step-down Converter, 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. TPS562209DDCT always operate in continuous conduction mode, which reduces the output ripple voltage in light load compared to discontinuous conduction mode.
