PTB78560C 具有自动跟踪定序的 30W 24V/48V 输入 DC/DC 转换器
PTB78560C 描述
The PTB78560x is a series of 30–W rated isolated dc/dc converters, designed to operate from a standard 24–V or 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 PTB78560 series incorporates Auto-TrackTM, a feature that simplifies the power-up sequencing of multiple power modules that operate 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 PTB78560 series is specifically designed to control the Track voltage of any number of nonisolated downstream modules powered from its output
