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
