Texas Instruments TPS563202 3A Synchronous Buck Converter
Texas Instruments TPS563202 3A Synchronous Buck Converter is a simple, easy-to-use converter in a SOT-563 package. The device is optimized to operate with minimum external component counts and to achieve low standby current. This switch-mode power supply (SMPS) device employs D-CAP2 mode control, providing a fast transient response. It also supports low-equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components. TPS563202 operates in ECO mode, maintaining high efficiency during a light load operation. Texas Instruments TPS563202 is available in a 6-pin 1.6mm × 1.6mm SOT563 (DRL) package and specified from a –40°C to 125°C junction temperature.
