Product details
Overview
AL1697-30BAS7-13 from Diodes Incorporated is a high-power-factor, boundary-conduction-mode (BCM) LED driver IC with integrated 400 V / 3 A Super-Junction MOSFET, ±3% current sense tolerance, and NEMA SSL6-compliant dimming curve for mains-dimmable LED lamps. It delivers precise constant-current regulation across wide input line (85–265 VAC) and load ranges while eliminating auxiliary winding and external HV MOSFET.
For engineers reviewing the AL1697-30BAS7-13 datasheet, AL1697-30BAS7-13 pinout, AL1697-30BAS7-13 application, or AL1697-30BAS7-13 equivalent, key selection criteria include internal MOSFET voltage/current rating (400 V / 3 A), thermal foldback trigger at +145°C, SO-7 package isolation spacing, and compatibility with leading/trailing-edge dimmers down to 1% dimming depth.
Technical Context
The AL1697-30BAS7-13 implements single-stage buck-boost topology with constant-on-time control to achieve >0.9 power factor and tight output current regulation. Its source-driver architecture reduces operating current to 170 µA at 4 kHz switching frequency, enabling low-loss VCC supply via output rectification without auxiliary winding.
Boundary conduction mode operation eliminates fixed-frequency EMI peaks and simplifies filter design. Internal protections include cycle-by-cycle OCP triggered at 1 V on CS pin, FB-based OVP/OSP, UVLO (14.5 V startup / 8.5 V minimum operating), and dual thermal safeguards: linear foldback starting at +145°C and latch-off OTP at +160°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VD Rating | 400 V drain-source breakdown - supports direct connection to 265 VAC mains with margin for transients |
| IDS (Continuous) | 3 A at TC = +25°C - enables driving LED strings up to ~25 W at 230 VAC input |
| RDS(ON) | 2.8 Ω typical - determines conduction loss and thermal rise in internal MOSFET |
| Current Sense Tolerance | ±3% - ensures accurate LED current regulation without external calibration |
| Startup Current | 130 µA - minimizes power loss during initial charge of VCC capacitor from high-voltage resistors |
| Thermal Foldback Start | +145°C junction temperature - linearly reduces output current to limit power dissipation before catastrophic failure |
| NEMA SSL6 Compliance | Verified dimming curve - guarantees smooth, flicker-free dimming performance with standard TRIAC dimmers |
Pinout & Package
AL1697-30BAS7-13 is housed in a SO-7 package with extended creepage distance between Drain (Pin 7) and low-voltage pins (GND, COMP, FB, CS) to meet reinforced insulation requirements for offline LED drivers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Internal LDO input and bias supply | Accepts 10–15.5 V; powers internal circuitry and gate driver; clamped at 15.5 V |
| 2 RT | External resistor connection for tON_MAX setting | Determines maximum on-time and thus dimming depth; 0.5 V reference enables precise timing control |
| 3 COMP | Error amplifier output | Drives internal MOSFET gate via transconductance amplifier; voltage range 0–4 V sets peak current limit |
| 4 GND | Analog and power ground reference | Common return for CS, FB, COMP, and internal circuits; requires low-impedance PCB layout |
| 5 FB | Output voltage feedback input | Monitors LED string voltage; triggers OVP/OSP when >4.0 V; leakage <4 µA ensures stable regulation |
| 6 CS | Current sense input | Measures MOSFET source current via R5; OCP activates at 1 V clamp; ±3% tolerance referenced to 0.4 V |
| 7 D | Drain of internal Super-Junction MOSFET | High-voltage switching node; rated 400 V / 3 A; isolated by SO-7 package spacing for safety compliance |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 400 V / 3 A Super-Junction MOSFET | Eliminates external HV switch and associated gate drive components, reducing BOM count and board area |
| Single-winding inductor topology | Removes need for auxiliary winding used in traditional flyback drivers, simplifying magnetics design and lowering cost |
| Boundary conduction mode (BCM) operation | Enables natural zero-current switching, minimizing EMI and easing EMC certification for Class B lighting products |
| Thermal foldback with +145°C trigger | Prevents thermal runaway by linearly scaling down LED current as junction temperature rises, extending system lifetime |
| Full protection suite | Includes UVLO, LEB, cycle-by-cycle OCP, OVP/OSP, and OTP - enables robust operation in unregulated AC environments |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL1697-20CS7-13 | 600 V / 2 A internal MOSFET; higher RDS(ON) (4 Ω typ) | Better suited for higher-line applications (230 VAC+), lower power (<15 W), or designs requiring higher voltage margin | Select when system peak drain voltage exceeds 350 V or thermal budget favors lower current density |
| AL1697-40DS7-13 | 670 V / 4 A internal MOSFET; lower RDS(ON) (1.8 Ω typ) | Supports higher-power LED loads (~35 W at 230 VAC) and wider input range including 305 VAC surge conditions | Choose for high-lumen commercial fixtures needing extended voltage headroom and reduced conduction loss |

FAQ
What dimmer types does AL1697-30BAS7-13 support?
The AL1697-30BAS7-13 supports both leading-edge (TRIAC) and trailing-edge (electronic low-voltage) dimmers. Its adaptive tON_MAX control enables deep dimming down to 1% while maintaining stable operation across diverse dimmer models, verified per NEMA SSL6 test methodology.
How is VCC supplied during low-dimming-angle operation?
During low-dimming-angle operation, VCC is maintained by rectified output voltage (via D2) rather than relying solely on startup resistors (R2/R3). This ensures continuous IC operation even when input conduction angle is minimal, preventing dropout and flicker.
What is the role of the RT pin and how is it configured?
The RT pin connects to an external resistor (R6) that sets tON_MAX - the maximum MOSFET on-time. With a 0.5 V internal reference and 1.5 pF internal capacitor, RT resistor value directly determines dimming depth and compatibility with specific dimmer hold-current requirements.
Does AL1697-30BAS7-13 require an auxiliary winding?
No. The AL1697-30BAS7-13 uses a source-driver technique and novel tOFF detection method that eliminates the need for an auxiliary winding. This reduces transformer complexity, lowers BOM cost, and improves system efficiency compared to conventional flyback LED drivers.
