• Output current capacity: 500mA per channel
• Single output configuration
• Flyback topology DC DC Controller architecture
• Analog and PWM dimming control capability
• Operating temperature range: -40°C to 125°C junction temperature

Mechanical Parameters:

• Package type: 10-SOP with 9 leads
• Physical dimensions: 0.154" width (3.90mm)
• Surface mount mounting type
• 9-SOIC supplier device package designation

Compliance Parameters:

• RoHS3 compliance requirement
• Moisture sensitivity level 1 (unlimited)
• Active product status

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes for the NCL30486B2DR2G.

Parameter Comparison

Engineering Selection Recommendations

The NCL30486B1DR2G serves as a direct parametric equivalent to the NCL30486B2DR2G. Both components share identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts is based on availability and inventory status rather than functional differences.
