TPP60508

60-V, 5-A, Non-Synchronous Step-Down DC/DC Converter

Overview

The TPP60508 is a 60-V, 5-A output, non-synchronous, step-down, and switch-mode converter with integrated high-side power MOSFET.

The TPP60508 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 TPP60508 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. By using opendrain power-good output, the user system is able to distinguish if the output supply is within the target voltage range. The soft-start feature, which controls the output ramping, can be set independently with external resistors to soft-start or sequencing/tracking mode. Current limit, frequency foldback, and over-temperature protection improve system-level robustness.
