VPTPCM-12 Series HIGH RELIABILITY COTS PRECONDITIONING MODULE DESCRIPTION FEATURES The VPTPCM-12 is a Pre-Conditioning Module which allows VPT's DV and VPT series isolated DCDC converters to operate over an extended input voltage range and provides compliance to both MILSTD-704 and MIL-STD-1275 input power requirements. A wide input voltage range accommodates both nominal 12V and 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 ensure long term reliability. High Reliability at Low Cost Up to 120 Watts of Output Power Wide Input Voltage Range: 9 to 40 Volts per MIL-STD-704 and MIL-STD-1275 Transient Operation down to 6 Volts and up to 100 Volts per MIL-STD-1275 High Efficiency, Up to 99% Inrush Current Limiting Input Undervoltage Lockout Fixed Frequency Output Soft Start Wide Temperature Range, -55C to 100C Internally Conformal Coated Six Sided Non-Hermetic Rugged Metal Enclosure The VPTPCM-12 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 the USA in a facility certified to ISO9001, J-STD-001 and IPC-A-610.

VPTPCM-12-3.0 7 VPTPCM-12 Series PACKAGE PIN DESCRIPTION Pin Function Description 1 VIN Positive Input Voltage Connection 2 VIN Positive Input Voltage Connection 3 INHIBIT This is an open collector input. Logic Low = Disabled Output. Connect the inhibit pin to input common to disable the output. Unconnected, open collector or open drain = Enabled Output. 4 INCOM Return Connection 5 INCOM Return Connection 6 OUTCOM Return Connection 7 CASE Case Connection 8 INH OUT This is an open collector output. It will activate low during a positive input voltage transient. It can be used as a status flag or connected to the Inhibit input of the downstream DC-DC converter to turn the converter off during a transient, when uninterrupted operation is not required. This connection is usually not required. This pin should be left open if not used. 9 N/C No Connection 10 VOUT Positive Output Voltage Connection 100% ENVIRONMENTAL SCREENING Screening Condition Internal Visual IPC-A-610 Stabilization Bake MIL-STD-883, Method 1008, Condition B, 125C, 24 hours Temperature Cycling MIL-STD-883, Method 1010, Condition B, -55C to +125C, 10 Cycles Burn-In 96 hours at +100C Final Electrical 100% at 25C External Visual Internal Procedure VPTPCM-12-3.0 8 VPTPCM-12 Series ORDERING INFORMATION VPTPCM- 12 1 2 (1) (2) Product Series Nominal Input Voltage VPTPCM 12 12 - 28 Volts CONTACT INFORMATION To request a quotation or place orders please contact your sales representative or the VPT Inc.
