3 Description
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.
