Product details
Overview
AL1692-30BS7-13 from Diodes Incorporated is a triac-dimmable, high-power-factor buck-boost/flyback LED driver IC with integrated 500V/3A MOSFET, ±3% current sense tolerance, boundary conduction mode (BCM) operation, and NEMA SSL6-compliant dimming down to 1%. It targets 120Vac mains-connected LED lamps requiring single-winding inductor design and reduced BOM cost.
For engineers reviewing the AL1692-30BS7-13 datasheet, AL1692-30BS7-13 pinout, AL1692-30BS7-13 application, or AL1692-30BS7-13 equivalent, key selection criteria include thermal foldback trigger at +145°C, VCC clamp at 15.5V, FB feedback voltage of 3.95V, tON_MAX programmability via RT pin, and SO-7 package thermal resistance (θJA = 123°C/W).
Technical Context
The AL1692-30BS7-13 implements constant-on-time (COT) control with source-driver architecture to achieve >0.9 power factor and high efficiency in BCM. Its internal 500V/3A MOSFET eliminates external HV switching components, while tOFF detection without auxiliary winding simplifies transformer design.
Protection logic integrates cycle-by-cycle OCP triggered at 1.6V CS clamp, UVLO startup at 14.5V with 8.5V minimum operating voltage, and dual thermal response: linear current reduction above +145°C (TFP) and latch-off shutdown at +160°C (OTP).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VD Rating | 500V drain-source breakdown - enables direct 120Vac input connection without external HV MOSFET |
| IDS Continuous | 3A drain current - supports up to ~30W LED loads in SO-7 package with thermal derating |
| Current Sense Tolerance | ±3% - ensures tight LED current regulation across line/load/temperature for consistent lumen output |
| VFB | 3.95V typical - sets overvoltage protection threshold and enables precise open-circuit detection |
| tON_MAX | 5.4µs max (RT = 51kΩ) - programmable dimming depth control via external resistor |
| Thermal Foldback | +145°C typical trigger - linearly reduces output current to maintain safe junction temperature under sustained high ambient |
| Startup Current | 100µA typical - minimizes power loss during initial charge of VCC capacitor from AC line |
Pinout & Package
AL1692-30BS7-13 is housed in a thermally enhanced SO-7 package (6.9mm × 3.9mm × 1.75mm), featuring exposed drain pad for improved heat dissipation and θJC = 19°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Internal bias supply input | Accepts 10–15.5V; powers internal circuitry; clamped at 15.5V to protect LDO and gate driver |
| 2 RT | Timing resistor connection | Sets maximum on-time (tON_MAX) for dimming depth control; referenced to 0.5V internal voltage |
| 3 COMP | Error amplifier output | Drives internal MOSFET gate; voltage range 0–4V determines current regulation setpoint |
| 4 GND | Power and signal reference | Common return for CS, FB, RT, and internal circuits; must be low-impedance PCB plane |
| 5 FB | Output voltage feedback | Monitors LED string voltage; triggers OVP/OSP when exceeding 3.95V; 4μA leakage limits divider loss |
| 6 CS | Primary-side current sensing | Measures MOSFET current via R5; 1.6V clamp prevents false OCP triggering during LEB period |
| 7 D | Drain of integrated MOSFET | High-voltage switching node; connects directly to primary winding; requires careful layout for EMI |
Key Features
| Feature | Design Value |
|---|---|
| NEMA SSL6 dimming compliance | Guarantees smooth 1–100% dimming with leading/trailing-edge dimmers without flicker or pop-on artifacts |
| Integrated 500V/3A MOSFET | Removes need for external HV switch and varistor, reducing BOM count by ≥3 components and PCB area |
| Single-winding inductor support | Eliminates auxiliary winding and associated rectifier/diode, lowering transformer cost and leakage inductance |
| Thermal foldback + OTP | Prevents thermal runaway: gradual current reduction above +145°C followed by hard shutdown at +160°C |
| Boundary conduction mode (BCM) | Enables high efficiency (>90%) and low EMI without complex frequency compensation or snubbers |

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 improved THD, lower standby current (50µA), and extended dimmer compatibility (including digital dimmers) | Designed for next-gen smart lighting with tighter regulatory compliance (IEC 61000-3-2 Ed.3) | Recommended for new designs; AL1692-30BS7-13 is not recommended for new designs per Diodes datasheet |
| BP57728 | Non-integrated HV MOSFET; requires external 650V switch; higher system BOM but wider input range (90–305Vac) | Better suited for universal-input (120/230Vac) LED drivers where AL1692-30BS7-13 is limited to 120Vac | Select when designing for global markets requiring dual-voltage operation or higher power density |
Compared with AL1692-30BS7-13, AL1698K offers lower system-level THD and longer dimmer compatibility at the cost of minor PCB layout changes, while BP57728 trades integration for universal input flexibility-making AL1692-30BS7-13 optimal only for cost-sensitive, 120Vac-only A19/BR30 lamp replacements.

FAQ
What is the maximum ambient temperature at which AL1692-30BS7-13 can operate continuously?
The device operates continuously up to +105°C ambient temperature under normal conditions. Above this, thermal foldback begins reducing output current at +145°C junction temperature. At +160°C junction, it enters latched shutdown and requires AC power cycle to recover. PCB layout with adequate copper pour on drain pad is essential to sustain performance near thermal limits.
Does AL1692-30BS7-13 require an auxiliary winding for tOFF sensing?
No. The AL1692-30BS7-13 uses an internal zero-current detection (ZCD) circuit that senses tOFF directly from the drain node, eliminating the need for an auxiliary winding or additional rectifier diode. This reduces transformer complexity, cost, and leakage inductance while improving reliability.
How is dimming depth adjusted on AL1692-30BS7-13?
Dimming depth is set by the external resistor (R6) connected to the RT pin, which programs tON_MAX. A larger RT value increases tON_MAX, allowing deeper dimming (down to 1%). The relationship is defined by tON_MAX = 3.3×VREF/0.33μA + RT×1.5pF, where VREF = 0.5V. Typical values range from 39kΩ to 68kΩ depending on target dimming curve.
Can AL1692-30BS7-13 be used in 230Vac applications?
No. The integrated 500V MOSFET and internal protection thresholds are optimized for 120Vac triac-dimmable lamp applications. For 230Vac, the peak line voltage exceeds the device's safe operating area, risking avalanche stress and premature failure. Diodes recommends BP57728 or AL1698K for universal-input designs.
