IW3616-01 Übersicht
An LED driver is an AC/DC or DC/DC power converter that delivers a regulated constant current to a string of LEDs, ensuring consistent luminance and protecting the LEDs from line-voltage transients. Two-stage architectures use a power-factor-correction (PFC) front end followed by an isolated or non-isolated DC/DC stage, which separates the high-frequency energy storage from the dimming interface. The iW3616 sits within the broader power management IC hierarchy: LED driver -> AC/DC controller -> power management IC -> semiconductor.
Key features of the IW3616-01 include flickerless dimming with both leading-edge (TRIAC) and trailing-edge (ELV) dimmer detection, IEC 61000-3-2 EMC compliance, Zhaga hot-plug interface compatibility, NEMA SSL 6 dimming curve mapping, and integrated protection (LED open-circuit, short-circuit, over-temperature, and over-voltage). The 200 kHz PWM switching frequency keeps the magnetic footprint small for compact lamp form factors.
The iW3616-01 applies advanced digital control to detect the dimmer type and phase angle, providing dynamic impedance to interface the dimmer and control LED brightness simultaneously. By using a BJT power device instead of a MOSFET, it reduces component count in protection circuits and enables lower-cost electrolytic capacitor usage, making it attractive for cost-sensitive residential and commercial retrofit bulb designs.
Typical applications include dimmable A19/E26/E27 retrofit bulbs, downlights, candelabras, and commercial troffers where flicker-free operation across a wide dimming range is mandatory. The high-PF and low-THD characteristics also make it suitable for regions enforcing strict harmonic current regulations such as the EU, California Title 24, and Energy Star requirements.
When designing with the IW3616-01, use the manufacturer's reference design to select the input bulk capacitor, BJT switch, and snubber components, and follow the layout guidelines to keep the high-current loop area small for EMI compliance.

Typische Anwendungen
IW3616-01 ist geeignet für 6 Anwendungs: Dimmable A19 LED Retrofit Bulb, Commercial Downlight / Troffer, Candle / Candelabra LED Lamp, Wall Sconce and Vanity Light, Under-Cabinet and Cove Lighting, Portable LED Work Light.
Dimmable A19 LED Retrofit Bulb
The IW3616-01 fits a dimmable A19/E26 retrofit bulb because its two-stage architecture delivers high power factor (>0.95) and low total harmonic distortion (<15%), which are the regulatory thresholds for residential mains-voltage LED lighting under Energy Star and EU regulations. Its digital dimmer-type detection supports both leading-edge TRIAC and trailing-edge ELV dimmers with mapping into the NEMA SSL 6 curve, which eliminates the flicker and pop-on problems that plague low-cost single-stage drivers. Place the controller between the bridge rectifier and the BJT-switch PFC stage, then drive the output electrolytic capacitor and LED string with the integrated DC/DC stage. The 200 kHz switching frequency keeps the magnetics small enough to fit inside the A19 form factor, and the 12 W ceiling is the sweet spot for an 8-10 W replacement of a 60 W incandescent.

Commercial Downlight / Troffer
For commercial 4-inch to 6-inch downlights and 2x2 / 2x4 troffers, the IW3616-01 is well matched because its low output ripple (<20%) and high PF keep the luminaire compliant with California Title 24 and ASHRAE 90.1 harmonic limits. The two-stage topology separates the high-frequency PFC bulk from the LED current regulation, which allows designers to use lower-cost aluminum electrolytic output capacitors instead of the long-life film capacitors required by single-stage drivers. The integrated OTP and OVP protect against the elevated ambient temperatures inside plenum-rated downlight housings, and the IEC 61000-3-2 EMC compliance streamlines UL/cUL and CE marking. The Renesas reference design provides a complete BJT-based schematic so a 12 W downlight can be prototyped in days rather than months.
Empfohlen
Candle / Candelabra LED Lamp
Candle and candelabra LED lamps have very tight PCB real estate and operate at 4-6 W, so the IW3616-01's compact SOIC-14 footprint and external BJT switch keep the driver board small enough to fit inside a E12/E14 base. The controller's two-stage operation ensures flicker-free dimming on the small-wattage loads where flicker is most visible to the human eye, and the NEMA SSL 6 dimming curve mapping delivers a smooth 5%-100% dimming range on standard wall dimmers. The BJT-switch architecture is more tolerant of the higher leakage inductances of the very small magnetics required for the candelabra form factor, and it dissipates less heat than a comparable MOSFET-based controller in this power range.

Wall Sconce and Vanity Light
Wall sconces and vanity lights in hospitality and residential settings are increasingly specified as dimmable LED fixtures, and the IW3616-01 provides the high-PF, low-THD dimming performance required by these installations. The integrated OVP and OTP are particularly important in enclosed sconce housings where heat builds up and surges on the line can be common, while the digital dimmer-type detection handles the wide variety of TRIAC dimmers installed in older buildings. The two-stage topology also allows the output current to be set precisely for a specific LED bin, which is critical for hospitality applications where color consistency across many rooms is a brand requirement.
Empfohlen
Under-Cabinet and Cove Lighting
Under-cabinet and cove lighting strips typically use 6-12 W of constant-current LED drive, and the IW3616-01's 12 W ceiling matches the upper end of these form factors. The flickerless dimming is particularly valued in under-cabinet installations in kitchens, where flicker is noticeable and bothers the user during food preparation. The 200 kHz switching frequency also keeps EMI out of the AM radio and DAB bands that may be present in adjacent kitchen electronics, and the IEC 61000-3-2 EMC compliance helps with CE marking for export to Europe. The BJT-switch architecture is also well suited to the higher ambient temperature in enclosed under-cabinet spaces.
Empfohlen
Portable LED Work Light
Portable LED work lights are typically mains-powered and need to tolerate a wide range of dimmer conditions in industrial and construction environments. The IW3616-01's robust digital dimmer-type detection is well suited to the dirty mains waveforms encountered on construction-site power, and the integrated OTP protects the BJT switch when the work light is operated in enclosed housings. The low ripple (<20%) and flickerless dimming are valued for long-duration work where eye strain is a concern. The SOIC-14 package is also easy to hand-rework during prototyping, which speeds the time from concept to production for a portable work-light SKU.

- Universal TRIAC and ELV dimmer compatibility (vs. Single-mode dimmer controllers)
Designhinweise
The IW3616-01 dissipates the majority of its losses in the external BJT power switch, not the controller IC itself. In a 12 W design at 120 VAC nominal input, the BJT may dissipate 0.5-1.0 W; keep the BJT's exposed collector pad soldered to a 0.5 sq-in minimum copper pour. The SOIC-14 controller typically dissipates below 200 mW and requires no additional heatsinking beyond the standard JEDEC JESD51 1-oz 4-layer reference board.
Keep the high-current loop between the bridge rectifier, the input bulk capacitor, the BJT switch, and the snubber network tight (<10 mm loop area) to avoid radiated EMI that would otherwise fail the IEC 61000-3-2 conducted and radiated emissions tests. Place the BJT base-drive resistor within 5 mm of the GATE pin, and route the CS sense line as a Kelvin trace to avoid false current-limit trips. The VCC decoupling cap must be within 3 mm of pin 1 with a direct via to the ground plane.
Do not omit the auxiliary winding on the PFC inductor - it provides the zero-current-detection (ZCD) timing for valley switching and the bootstrap rail for the controller. Without the auxiliary winding the controller will not start reliably and the OVP threshold will not be detected. Also, ensure the DIM pin is properly biased with the recommended pull-up/pull-down network; floating the DIM pin disables dimmer detection and may trigger the fault latch during line transients.
Route the FB and CS analog traces on the inner layer with a continuous ground plane below to minimize noise coupling. Keep the analog ground (GND pin 2) and the power ground (BJT emitter and bulk cap negative) joined at a single point near the bulk capacitor negative terminal. The OT/OV fault pin should be left unconnected if the protection features are unused, per the Renesas reference design.
