Product Details

The IQ65033QMA10 iQor Power Interface Module integrates all features required by the AdvancedTCA Base Specification into a Quarter-Brick footprint. The iQor offers industry leading external hold-up capacitor volumetric density for a compact overall solution. At a 90V hold‑up capacitor voltage (trimmable 50-95 V), only 564 μF is required to achieve 8.70ms hold‑up time at 200Win. The -48 V output voltage is conditioned for smooth operation through severe input transient events. The iQor is designed thermally and electrically to drive high power wide-range-input DC/DC converters such as the 300 W SynQor PQ60120QEA25. RoHS Compliant see last page.

Operational Features

• Input ORing for A & B power feeds (MOSFET-based for low power dissipation)
• Hot swap control with seamless ride-through of input voltage transient
• EMI filter meets CISPR 22 Class B when used as directed (see applications section)
• External hold-up capacitor trimmable from 50-95 V
• Automatic discharge of external hold-up capacitor
• Isolated management power of 3.3 V at 3.6 A and 5.0 V at 150 mA
• Dual input side enable
• I2C interface data reporting (optional)

Mechanical Features

• Industry standard quarter-brick size: 1.45" x 2.3" (36.8x58.4 mm)
• Overall height of 0.54" (13.7 mm), permits better airflow and smaller card pitch
• Total weight: 1.2 oz (34 g)
• Flanged pins designed to permit surface mount soldering (avoid wave solder) using FPiP technique
• External hold-up capacitor footprint much smaller than other solutions currently available on the market

Safety Features

• 2250V, 30 MΩ VRTN_A/B to LOGIC_GND and SHELF_GND isolation
• UL 60950-1
• CAN/CSA-C22.2 No. 60950-1
• EN 60950-1

Protection Features

• Management power over-voltage protection
• Management power over-current protection
• Main output over-current protection
• Thermal shutdown protects the unit from abnormal environmental conditions
• Active back bias limit
• Input fuse/feed loss alarm
