DescriptionThe TPS561201DDCR and TPS561208 are simple, easy-to-use, 1-A synchronous step-down convertersin SOT-23 package.
The devices are optimized to operate with minimum external component counts and alsooptimized to achieve low standby current.
These switch mode power supply (SMPS) devices employ D-CAP2 mode control providing a fasttransient response and supporting both low equivalent series resistance (ESR) output capacitorssuch as specialty polymer and ultra-low ESR ceramic capacitors with no external compensationcomponents.
The TPS561201DDCR operates in pulse skip mode, which maintains high efficiency during lightload operation. The TPS561201DDCR and TPS561208 are available in a 6-pin 1.6 × 2.9 (mm) SOT (DDC)package and specified from –40°C to 125°C of junction temperature.
