The Ultimate Guide to the VLC 1600 Datasheet: Specifications, Applications, and Technical Deep Dive

4.3 Using the Monitor Photodiode (APC Circuit)

The integrated photodiode enables Automatic Power Control (APC) . A sample circuit from a typical VLC 1600 datasheet:

               [Current Sense Resistor]
                │
               [MOSFET / BJT Pass Transistor]
                │
Laser Cathode ─┼──> To ground via driver IC
                │
Photodiode A ──┼──> To op-amp inverting input
                │
Photodiode K ──┴──> To op-amp non-inverting reference (APC setpoint)

The APC loop maintains constant optical power by adjusting the drive current, compensating for temperature-induced efficiency drops.

1. Description

The VLF1600 series comprises shielded SMD power inductors designed for high current applications. These components utilize a magnetic iron powder core and are magnetically shielded to minimize radiation and interference with surrounding circuits. They are optimized for use in DC/DC converters, power supplies, and voltage regulator modules (VRMs). The Ultimate Guide to the VLC 1600 Datasheet:

(Note: "VLC" is a common typo for "VLF" when reading logos or low-resolution datasheets. If you require data for a specific inductance value, please verify the full part number printed on the component.)

6.2 Medical Laser Therapy (Dental / Surgical)

At 1600 mW, the VLC 1600 can be used in low-level laser therapy (LLLT) or cauterization. The datasheet will caution:

• Duty cycle must not exceed 30% if passive cooling is used.
• A fiber coupler with 200µm core diameter is recommended.
