3 Description
The TPS65266-1 incorporates 3 channels of high-
efficiency
synchronous
buck
converter
for
applications operating off the adaptor or battery with
input voltage lower than 6 V.
The
buck
DC/DC
converter
integrates
power
MOSFETs
for
optimized
power
efficiency
and
reduces
external
component
counts.
The
peak
current mode control simplifies the compensation and
fast transient response. High clock frequency allows
smaller and low-value inductors and capacitors.
External
compensation
supports
optimized
loop
compensation and fast transient response. In light
load condition, the buck converter operates in PSM
mode for a reduction on the input power supplied to
the system. Cycle-by-cycle overcurrent limiting with
hiccup mode limits MOSFET power dissipation in
short circuit or overloading fault conditions.
The TPS65266-1 features a power-good supervisor
circuit that monitors all converter outputs. The
PGOOD pin is asserted after the output voltages in
each channel are in regulation and sequencing is
done.
When continuous heavy overload or short circuit
increases power dissipation in the buck converter,
internal thermal protection circuit shuts off the device
to
prevent
damage.
Recovery
from
a
thermal
shutdown is automatic after the device has cooled
sufficiently.
