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-Track, 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 output. This ensures that the outputs of the downstream modules all rise simultaneously during
power up. The PTB48560B (3.3 V) has an additional sequenced output, VO Seq, which also rises with the Track
voltage. This allows the VO Seq output to power up simultaneously with the outputs from other power modules
under the control of Auto-Track.
Whether used to facilitate power-up sequencing, or operated as a stand-alone module, the PTB48560 series
includes many other features expected of high-performance dc/dc converter modules. Precise output voltage
regulation is ensured with a differential remote sense. Operational features include an input undervoltage lockout
(UVLO) and a dual-logic output enable control. Overcurrent and overtemperature protection ensure survival
against load faults.Typical applications include distributed power architectures in both telecom and computing
environments, particularly complex digital systems requiring power sequencing of multiple power supply rails.
