These modules operate from a standard telecom (–48 V) central office (CO) supply to produce two independantly regulated outputs. The PT4660 series is characterized with high efficiencies and ultra-fast transient response, and incorporates many features to facilitate system integration. These include a flexible “On/Off” enable control, output current limit, over-temperature 30-A Dual Output Isolated DC/DC Converter Features • Dual 15-A Outputs (Independantly Regulated) • Power-up/Down Sequencing • Input Voltage Range: 36 V to 75 V • 1500 VDC Isolation • Temp Range: –40 to 100 °C • High Efficiency: 88 % • Fixed Frequency Operation • Over-Current Protection (Both Outputs) Ordering Information Pt.

In addition, both output voltages are designed to meet the power-up/power-down sequenc- ing requirements of popular DSPs. The PT4660 series is housed in space-saving solderable copper case. The package does not require a heatsink and is available in both vertical and horizontal configura- tions, including surface mount. The ‘N’ configuration occupies less than 2 in² of PCB area.
