3 Description
The TPS562209 and TPS563209 are simple, easy-to-
use, 2-A and 3-A synchronous step-down converters
in 6 pin SOT-23 package.
The 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.
TPS562209 and TPS563209 always operate in
continuous conduction mode, which reduces the
output ripple voltage in light load compared to
discontinous conduction mode. TPS56x209 are
available in a 6-pin 1.6 × 2.9(mm) SOT (DDC)
package, and specified from –40°C to 150°C of
junction temperature.
