3 Description
The TPS631012 and TPS631013 are constant
frequency peak current mode control buck-boost
converters in tiny wafer chip scale package. They
have a 3-A peak current limit (typical) and 1.6-V
to 5.5-V input voltage range, and provide a power
supply solution for system pre-regulators and voltage
stabilizers.
Depending on the input voltage, the TPS631012 and
TPS631013 automatically operate in boost, buck, or
in 3-cycle buck-boost mode when the input voltage
is approximately equal to the output voltage. The
transitions between modes happen at a defined
duty cycle and avoid unwanted toggling within the
modes to reduce output voltage ripple. 8-μA quiescent
current and power save mode enable the highest
efficiency for light to no-load conditions.
The devices offer a very small solution size in WCSP.
