Texas Instruments TPS563208

Beschreibung

The TPS563201 and TPS563208 are simple, easy-to-use, 3 A synchronous step-down converters in SOT- Integrated 95-mΩ and 57-mΩ FETs 23 packageThe devices are 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.TPS563201 operates in pulse skip mode, which maintains high efficiency during light load operation. The TPS563201 and TPS563208 are 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.
