The TPSM83100, TPSM83101, and TPSM83101L are
constant frequency peak current mode control buck-boost MicroSiP™ power modules optimized for
small design size and high efficiency. The power modules integrate an inductor to simplify
design, reduce external components, and save PCB area. The power modules have a 3A peak
current limit (typical) and 1.6V to 5.5V input voltage range. The TPSM83100 and TPSM83101,
TPSM83101L provide a power supply design for system pre-regulators and voltage
stabilizers.
Depending on the input voltage, the TPSM83100 and
TPSM83101, TPSM83101L 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. 8µA quiescent current and power save mode enable the highest
efficiency for light to no-load conditions.
