Key Document


The TPS563249 is a simple, easy-to-use, 3-A synchronous step-down converter in SOT-23 package. The device is optimized to operate with minimum external component counts and also optimized to achieve low standby current. This switch mode power supply (SMPS) device employs 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.TPS563249 operates in Forced Continuous Conduction Mode (FCCM), which maintains fixed 1.4-MHz switching frequency during light load operation and eliminates system interference. The TPS563249 is available in a 6-pin 1.6-mm × 2.9-mm SOT (DDC) package, and specified from a –40°C to +125°C junction temperature.
