PTB48560B 具有自动跟踪定序的 30W 48V 输入 DC/DC 转换器

PTB48560B 描述

The PTB48560x is a series of 30-W rated isolated dc/dc converters, designed to operate from a standard -48-V telecom central office (CO) supply. Housed in a 1×2 package, each model has a wide-adjust output voltage that can be set to one of the common intermediate bus voltages of 3.3 V, 5 V, or 12 V.

The PTB48560 series incorporates Auto-TrackTM, a feature that simplifies the power-up sequencing of multiple power modules and operates from the same intermediate bus. During a power-up cycle, modules with this feature have the capability of following a common ramp voltage applied to an input called Track. The PTB48560 series is specifically designed to control the Track voltage of any number of nonisolated downstream modules powered from its
