The TPS562219A and TPS563219A are simple, easy-to-use, 2-A, 3-A synchronous step-down converters in 8 pin SOT-23 package.
The devices are optimized to operate with minimum external component counts and 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.
The devices always operate in continuous conduction mode, which reduces the output ripple voltage in light load compared to discontinuous conduction mode . The TPS562219A and TPS563219A are available in a 8-pin 1.6 × 2.9 (mm) SOT (DDF) package, and specified from –40°C to 85°C of ambient temperature.
