PT4663A [Rochester]

The PT4660 series is a 30-A rated, dual-output isolated DC/DC converter that operates from a standard telecom (–48 V) central office (CO) supply to produce two independently regulated outputs. It features high efficiencies and ultra-fast transient response, and incorporates many features to facilitate system integration, including flexible On/Off enable control, output current limit, over-temperature shutdown, and an input under-voltage lockout (UVLO). Both output voltages are designed to meet the power-up/power-down sequencing requirements of popular DSPs. The module is housed in a space-saving solderable copper case and is available in vertical, horizontal, and surface mount configurations.
