Description
The TPP20608x is a series of 17-V, 6-A output,
synchronous, step-down, switch-mode converters with
integrated power MOSFETs.
The TPP20608x series employs current mode control
supporting simple external compensation and flexible
component selection. With the integrated phase-locked
loop, the TPP20608x series can synchronize with external
clock source with wide frequency selection, optimized
for efficiency, physical dimensions, and electromagnetic
interference (EMI).
Protection and diagnostics features protect the device as
well as the system power supply. By using open-drain
power-good output, the system is able to distinguish
if the output supply is within the target voltage range.
Soft-start features, which control the output ramping,
can be set independently by an external resistor or
to sequencing/tracking mode. Current-limit and overtemperature protection improve system-level robustness
