• DC-DC Regulator topology with Switched Capacitor (Charge Pump) architecture
• Exactly 5 output channels
• Supply voltage range: 2.8V to 5.5V
• Output current per channel: 20mA
• Operating frequency: 1MHz
• Multi-step dimming capability
• Internal integrated switches

Mechanical Parameters:

• Package type: 16-VFQFN with Exposed Pad
• Physical footprint: 3x3mm QFN
• Surface mount configuration

Compliance & Environmental:

• Operating temperature range: -40°C to 85°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• REACH unaffected status

Only parts meeting all these parameters simultaneously qualify as true parametric equivalents.

Engineering Selection Recommendations

The AP3615FNTR-G1 is the primary part number for this LED driver IC application. Both the main part and its parametric equivalent share identical specifications across all electrical, mechanical, and compliance parameters. Selection between equivalent parts should be based on:

Product Status: Both parts maintain active production status, ensuring long-term availability and supply chain stability.

Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for commercial and industrial applications.

Moisture Sensitivity: MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling, simplifying logistics and inventory management.

Supply Chain Considerations: With 15,400 pcs in current inventory, the AP3615FNTR-G1 offers immediate availability for production requirements.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the AP3615FNTR-G1? A: A valid substitute must match all electrical parameters (5-output DC-DC regulator, switched capacitor topology, 2.8V-5.5V supply range, 20mA per channel, 1MHz frequency, multi-step dimming), mechanical specifications (16-VFQFN 3x3mm package), and compliance certifications (ROHS3, REACH unaffected, MSL 1).

Q: Can I use a different package variant of the AP3615? A: No. The 16-VFQFN Exposed Pad (3x3mm) package is a critical specification. Different package types (such as alternative QFN sizes or BGA variants) are not interchangeable without PCB redesign and re-qualification.

Q: Is the AP3615FNTR-G1 suitable for applications outside of backlight? A: The part is specified for backlight applications. Use in other applications requires evaluation against the device's electrical characteristics and thermal performance in the target application context.

Q: What is the significance of the MSL 1 rating? A: MSL 1 (Unlimited) means the component has no moisture sensitivity limitations. It can be stored indefinitely without desiccant packaging or special environmental controls, simplifying supply chain handling.

Q: Are there any lead-free or RoHS alternatives? A: The AP3615FNTR-G1 is already ROHS3 compliant, meeting lead-free and hazardous substance restrictions. No alternative qualification is necessary for RoHS compliance.

Q: What is the exposed pad function in the 16-VFQFN package? A: The exposed pad provides thermal and electrical connection to ground, improving heat dissipation and electrical performance. It must be soldered to the PCB ground plane during assembly.
