Product details
Overview
AL1692L-30B1S7-13 from Diodes Incorporated is a triac-dimmable, high-power-factor buck-boost/flyback LED driver IC integrating a 500V/3A high-voltage MOSFET in SO-7 package. It delivers ±3% output current accuracy over wide line/load variations, operates in boundary conduction mode (BCM), and supports deep dimming down to 1% with NEMA SSL6-compliant curve for 120Vac lamp applications.
For engineers reviewing the AL1692L-30B1S7-13 datasheet, AL1692L-30B1S7-13 pinout, AL1692L-30B1S7-13 application, or AL1692L-30B1S7-13 equivalent, key selection criteria include integrated HV MOSFET capability, thermal foldback trigger at +145°C, 0.4V internal current-sense reference, tON_MAX programmability via RT pin, and compatibility with leading/trailing-edge dimmers without auxiliary winding.
Technical Context
The AL1692L-30B1S7-13 implements constant-on-time (COT) control with source-driver architecture to achieve high power factor (>0.9) and eliminate need for auxiliary winding. Its BCM operation enables predictable EMI behavior and simplifies filter design while maintaining >90% efficiency across dimming range.
Internal protections include cycle-by-cycle OCP triggered at 1.6V CS clamp, UVLO with 14.5V startup and 8.5V operating threshold, and dual thermal response: linear current foldback starting at +145°C and latch-off OTP at +160°C. Feedback uses FB pin for open-circuit detection with 3.95V typical OVP threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VD Rating | 500V drain-source breakdown voltage - enables direct 120Vac input connection without external HV MOSFET or varistor |
| IDS | 3A continuous drain current - supports up to 30W LED loads in compact SO-7 package |
| VREF | 0.4V internal current-sense reference - sets output current precision via R5 with ±3% tolerance |
| tON_MAX | 5.4µs max on-time (RT = 51kΩ) - programmable dimming depth and compatibility with diverse TRIAC dimmers |
| VFB | 3.95V typical feedback threshold - provides LED open-circuit protection and hiccup-mode recovery |
| TFOLD | +145°C thermal foldback trigger - linearly reduces output current to maintain safe junction temperature |
| IST | 100µA typical startup current - minimizes standby losses and enables reliable cold-start under low-dimming-angle conditions |
Pinout & Package
AL1692L-30B1S7-13 is housed in a thermally enhanced SO-7 package with exposed pad for improved heat dissipation. Pin 7 (D) connects directly to the integrated 500V/3A MOSFET drain; Pin 1 (VCC) supplies internal bias; Pin 4 (GND) serves as primary ground reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Internal bias supply input | Accepts 10–15.5V regulated supply; powers gate driver and control logic; clamped internally at 15.5V |
| 2 RT | Maximum on-time programming node | Connects external resistor to set tON_MAX; internal 0.5V reference enables precise dimming depth calibration |
| 3 COMP | Error amplifier output | Drives internal MOSFET gate via source-driver; voltage range 0–4V determines peak current limit during dimming |
| 4 GND | Power and signal ground | Common return path for CS, FB, and internal circuitry; requires low-impedance PCB layout |
| 5 FB | Output voltage sensing input | Detects LED string open condition; triggers OVP when voltage exceeds 3.95V; enables hiccup-mode recovery |
| 6 CS | Current sense input | Monitors inductor current via R5; 1.6V clamp prevents false OCP triggering; supports cycle-by-cycle protection |
| 7 D | Integrated MOSFET drain | Direct connection to primary-side inductor; rated 500V/3A; eliminates need for external HV switch and snubber components |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 500V/3A MOSFET | Reduces BOM count by eliminating external HV switch, varistor, and associated gate drive components |
| NEMA SSL6 dimming compliance | Ensures smooth, flicker-free dimming down to 1% across leading- and trailing-edge dimmers without recalibration |
| Single-winding inductor support | Removes auxiliary winding requirement, simplifying magnetics design and reducing transformer cost and size |
| Thermal foldback protection | Linearly scales output current from full value at +25°C to zero at +145°C, enabling robust thermal management in enclosed fixtures |
| Boundary conduction mode (BCM) | Guarantees zero-current switching, minimizing EMI and enabling smaller input filters compliant with EN55015/CISPR15 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dimmable LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL1698K | Successor device with enhanced EMI performance, lower standby current (50µA), and extended thermal foldback range (+135°C to +155°C) | Designed for next-generation smart LED lamps requiring tighter THD and higher reliability under sustained high-temp operation | Recommended for new designs; offers pin-to-pin compatibility but requires updated RT and CS resistor values per DS40211 |
| BP5758D | Non-integrated HV MOSFET; requires external 650V switch; higher system component count; no built-in TFP | Better suited for 230Vac global applications where higher voltage margin is needed, but lacks thermal foldback linearity | Consider only if 500V rating is insufficient; requires additional gate driver, snubber, and thermal monitoring circuitry |
Compared with AL1692L-30B1S7-13, AL1698K improves thermal management fidelity and reduces no-load consumption, while BP5758D trades integration for higher voltage headroom-making AL1692L-30B1S7-13 optimal for cost-sensitive 120Vac TRIAC-dimmable lamps where compactness and dimming linearity are critical.

FAQ
What is the maximum recommended ambient temperature for continuous operation?
The AL1692L-30B1S7-13 supports continuous operation up to +105°C ambient temperature under normal conditions. At +125°C ambient, operation is possible only if thermal foldback prevents junction temperature from exceeding +150°C. The device enters latch-off OTP at +160°C junction temperature, requiring AC power cycle to recover.
How does the RT pin configure dimming depth?
The RT pin sets tON_MAX using an external resistor (R6); a 51kΩ resistor yields 5.4µs maximum on-time. Lower resistance increases tON_MAX, extending dimming range but potentially reducing compatibility with fast-turn-off trailing-edge dimmers. The relationship follows tON_MAX = 3.3 + 0.33 × RRT × 10−6 seconds.
Can AL1692L-30B1S7-13 operate without an auxiliary winding?
Yes. The AL1692L-30B1S7-13 uses source-driver architecture and novel tOFF detection to eliminate the auxiliary winding required by conventional flyback controllers. This reduces transformer complexity, lowers cost, and improves reliability in space-constrained lamp designs.
What protection features prevent LED string failure?
The AL1692L-30B1S7-13 provides output-open protection via FB pin monitoring (OVP at 3.95V), output-short protection via forced 4kHz low-frequency operation, and cycle-by-cycle OCP triggered at 1.6V on CS pin. Thermal foldback linearly reduces current above +145°C to prevent thermal runaway during prolonged overtemperature events.
