The TPS563211 is a cost
effective and highly flexible synchronous buck converter that provides selectable
Eco-mode operation or FCCM (Force Continuous Conduction Mode) operation. A
selectable Power-Good indicator or external soft start is also configurable through
the MODE pin. Power sequencing is possible by correctly configuring Enable,
Power-Good indicator, or external soft start. A wide input voltage range of 4.2 V to
18 V supports a wide variety of common input rails like 12 V and 15 V. It supports
up to 3-A continuous output current at output voltages between 0.6 V and 7
V.The device provides fast transient
response with true fixed switching frequency through the use of the Advanced
Emulated Current Mode (AECM) control topology. With internal smart loop bandwidth
control, the device provides fast transient response over a wide output voltage
range without the need for external compensation.Cycle-by-cycle current limit on the
high-side peak current protects the device in overload situations and is enhanced by
a low-side valley current limit, which prevents current runaway. Hiccup mode would
be triggered under overvoltage protection (OVP), undervoltage protection (UVP), UVLO
protection, and thermal shutdown.The device is available in 1.6-mm ×
2.1-mm SOT583 package.
