The TPS631000 is a constant frequency peak current
mode control buck-boost converter. The device has a 3A peak current limit (typical)
and 1.6V to 5.5V input voltage range. The TPS631000 provides a power supply design
for system pre-regulators and voltage stabilizers.
Depending on the input voltage, the
TPS631000 automatically operates 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. 8µA quiescent current and power save mode
power enable the highest efficiency for light to no-load conditions.
The TPS631000 offers a very small
design size with a 1.2mm × 2.1mm SOT-583 package, a 1µH inductor, and one 0805
output capacitor.
