100 W, dual outputs of 12 V, 15 V

-55 °C to 100 °C Operation

1.0 DESCRIPTION

The VPT100+ series of isolated COTS DC-DC converters is a cost effective solution for many demanding high reliability applications. A wide input voltage range accommodates nominal 28V inputs including avionics, mobile, ground systems, and other applications. A high efficiency design reduces input power requirements and eases thermal management. Low input and output ripple, fixed operating frequency, and companion EMI filters simplify system design and compliance. A proven design heritage, no optoisolators and a rugged all metal package ensures long term reliability. The VPT100+ series is intended for harsh environments including severe vibration, shock and temperature cycling. Testing is to JESD22, MIL-STD-810, and MIL-STD-883. These converters are designed and manufactured in a facility certified to ISO9001, J-STD-001 and IPC-A-610. This product may incorporate one or more of the following U.S. patents: 5,784,266 5,790,389 5,963,438 5,999,433 6,005,780 6,084,792 6,118,673

7.0 OUTPUT VOLTAGE TRIM

The output voltage can be trimmed down by connecting a resistor between the TRIM pin and the +VOUT pin, or can be trimmed up by connecting a resistor between the TRIM pin and the OUTCOM pin as shown in Section 2.2. The maximum trim range is +10% up and –20% down. The appropriate resistor values versus the output voltage are given in the trim table below.
