Product details
Overview
AL1692-30BAS7-13 from Diodes Incorporated is a triac-dimmable LED controller IC implementing boundary conduction mode (BCM) buck-boost and flyback topologies, delivering ±3% output current accuracy, 14.5V startup threshold, and NEMA SSL6-compliant dimming down to 1% with external MOSFET support up to 25W in mains-powered LED lamp designs.
For engineers reviewing the AL1692-30BAS7-13 datasheet, AL1692-30BAS7-13 pinout, AL1692-30BAS7-13 application, or AL1692-30BAS7-13 equivalent, this controller provides verified thermal foldback at +145°C, cycle-by-cycle OCP via CS pin, and SO-8 package compatibility for 120/230Vac offline LED drivers requiring high power factor and EMI-constrained environments.
Technical Context
The AL1692-30BAS7-13 operates in boundary conduction mode using constant on-time control to achieve >0.9 power factor and tight line/load regulation without auxiliary winding sensing. Its tON_MAX is set by an external RT resistor (51kΩ typical), enabling precise dimming depth control across leading- and trailing-edge dimmers.
Internal protections include UVLO (14.5V startup / 8.5V minimum operating), 1.6V CS clamp for OCP, 4.0V FB reference for OVP/OSP, and self-adaptive thermal foldback triggered at +145°C junction temperature - all implemented in a single-stage, single-winding architecture.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dimmable LED controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL1692-20CS7-13 | Integrates 600V/2A MOSFET in SO-7; no external switch required | Limited to ≤15W output due to thermal constraints of integrated FET | Select when board space is constrained and output power ≤15W; avoids MOSFET selection and layout complexity |
| AL1693S-13 | Higher 16.5V startup threshold; adds active bleeder control pin | Optimized for low-THD designs with active bleeder circuits; not drop-in compatible | Select when designing for Class C IEC 61000-3-2 compliance with <10% THD at full load |
Compared with AL1692-20CS7-13 and AL1693S-13, the AL1692-30BAS7-13 offers higher output power scalability (up to 25W), broader dimmer interoperability without active bleeder dependency, and SO-8 package thermal performance advantageous for thermally demanding enclosures.

FAQ
What is the maximum output power achievable with AL1692-30BAS7-13?
The AL1692-30BAS7-13 supports up to 25W output power when paired with an appropriately rated external MOSFET and heatsinked PCB layout. This rating assumes 120/230Vac input, 85°C ambient, and proper thermal management per Diodes' recommended SO-8 pad layout (2oz copper, 1"×1" FR-4).
Does AL1692-30BAS7-13 require an auxiliary winding for tOFF detection?
No. The AL1692-30BAS7-13 uses an internal zero-current detection (ZCD) circuit that eliminates the need for an auxiliary winding. This simplifies transformer design, reduces component count, and improves reliability in compact LED lamp form factors.
How does thermal foldback operate in AL1692-30BAS7-13?
At +145°C typical junction temperature, AL1692-30BAS7-13 begins linearly reducing its internal current reference voltage (VREF), thereby scaling down LED output current proportionally. This prevents thermal shutdown while maintaining safe operating temperatures in enclosed luminaires.
Can AL1692-30BAS7-13 drive both buck-boost and flyback topologies?
Yes. The AL1692-30BAS7-13 is explicitly validated for both buck-boost and flyback configurations per Diodes DS39008 Rev. 3–2. Its SW pin drives external low-side MOSFETs in either topology, with separate reference schematics provided for each in the datasheet.
