Description

The TPP60308 is a 60-V, 3.5-A output, non-synchronous,

step-down, and switch-mode converter with integrated

high-side power MOSFET.

The TPP60308 employs current-mode control supporting

simple external compensation and flexible component

selection. It also supports low quiescent current mode with

pulse-skipping and ultra-low sleep current.

With the integrated phase-locked loop, the TPP60308

can synchronize with an external clock source with wide

frequency selection, optimized for efficiency, physical

dimensions, and electromagnetic interference (EMI).

Protection and diagnostic features protect the device

as well as the system power supply. The soft-start

feature controls the output ramping. Current limit,

frequency foldback, and over-temperature protection

improve system-level robustness.
