3 Description
The TPS562210A and TPS563210A 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 operate in Advanced Eco-mode™, which
maintains high efficiency during light load operation.
The TPS562210A and TPS563210A 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.
