1. Product Identification & Overview:
️· Model: Q48SK12448NNFB
️· Type: DC-DC Converter
️· Form Factor: Through-hole
️· Input Voltage: 46-60V DC
️· Output Voltage: 12.0V DC
️· Output Current: 50A
️· Efficiency: 96.2% (at 54Vin, 12Vdc @ 50A)
️· Product Series: High Power
️· Option Code: F (RoHS 6/6 – Lead Free), B (Heat Spreader)
2. Pinout and Functions:
️· Pin 1: +Vin (Positive Input Voltage)
️· Pin 2: ON/OFF (Remote ON/OFF Control)
️· Pin 3: -Vin (Negative Input Voltage)
️· Pin 4: -Vout (Negative Output Voltage)
️· Pin 5: +Vout (Positive Output Voltage)
️· Pin Length Options: 0.145" or 0.197"
️· Pin Material: Copper with Matte Tin Plating and Nickel Underplating
3. Remote ON/OFF Control:
️· Can be controlled via an external switch (open collector or open drain) between the ON/OFF terminal and -Vin.
️· If not used, short the ON/OFF pin to -Vin.
4. Thermal Considerations:
️· Heat Management: Proper cooling is critical for reliability. Convection cooling is dominant.
️· Wind Tunnel Testing: Modules are tested in a wind tunnel to simulate realistic operating conditions.
️· Thermal Derating: Operate below the maximum operating temperature to ensure reliability.
️· Thermal Testing Setup: Heat spreader, airflow, and ambient temperature measurements were taken to create the thermal curve.
️· Maximum Hot Spot Temperature: 110°C.
5. Mechanical Details:
️· Intended for wave soldering.
️· Do not subject to reflow temperature profiles.
6. Regulatory & Warranty:
️· RoHS Compliant: (6/6 – Lead Free)
️· Warranty: 2-year limited warranty (full details available upon request).
