Product details
Overview
AP1690MTR-G1 from Diodes Incorporated is a single-stage primary-side regulation (PSR) power factor correction (PFC) controller for dimmable LED drivers. It delivers accurate constant-current (CC) regulation without opto-coupler or secondary feedback, supports universal AC input (85–265 VAC), achieves IEC61000-3-2 compliance, and integrates dimmer phase detection via PD/DIM pins for TRIAC/leading-edge compatibility.
For engineers reviewing the AP1690MTR-G1 datasheet, AP1690MTR-G1 pinout, AP1690MTR-G1 application, or AP1690MTR-G1 equivalent, this controller enables compact, cost-effective, high-efficiency LED driver designs with tight CC regulation, built-in protection (OVP, OCP, OTP, LED open/short), and elimination of loop compensation circuitry.
Technical Context
The AP1690 operates in quasi-resonant (QR) PFM mode with adaptive peak current control and acceleration start logic. Its FB pin monitors auxiliary winding voltage to regulate output current and manage no-load voltage, while CS pin senses primary current for cycle-by-cycle overcurrent protection and minimum on-time enforcement (500–1000 ns).
Dimming functionality relies on dual-input sensing: PD pin detects rectified AC phase angle for TRIAC synchronization, and DIM pin reads average input voltage to scale output current proportionally. Internal UVLO (18–20 V start, 7–9 V hold) and VCC OVP (28–36 V) ensure robust startup and rail safety.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Single-stage PSR PFC with QR-PFM control - eliminates secondary feedback and simplifies BOM |
| Input Voltage Range | 85–265 VAC universal - enables global mains compatibility without manual range switching |
| CC Regulation Accuracy | ±3% typical over line/load/temp - ensures consistent LED brightness across operating conditions |
| VCC Operating Range | 9–21 V - supports wide auxiliary supply margin and stable gate drive under transient loads |
| Start-up Current | ≤100 µA - reduces startup energy loss and enables smaller VCC capacitor |
| Thermal Protection | Junction temperature cutoff at +150°C - prevents thermal runaway during overload or poor heatsinking |
| OVP Threshold (FB) | 4.5–7.5 V - protects against output overvoltage due to transformer saturation or load removal |
Pinout & Package
AP1690MTR-G1 is housed in an SO-8 package (6.20 × 5.10 × 1.75 mm, 1.27 mm pitch), RoHS-compliant and halogen-free per Diodes Inc. Green standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NC | No connection | Unused pad - must remain unconnected to avoid interference with internal biasing |
| 2 PD | Phase-dimming detection input | Senses rectified AC waveform zero-crossing and conduction angle for TRIAC dimmer synchronization |
| 3 DIM | Average input voltage sense | Reads RMS-equivalent voltage to scale LED current linearly with dimmer position |
| 4 CS | Primary current sense | Monitors MOSFET source current for peak-current limiting and OCP triggering at 3–4 V |
| 5 FB | Auxiliary winding feedback | Derives output voltage/current info for PSR control; sets acceleration stop point and no-load OVP |
| 6 GND | Power and signal reference | Common return for gate driver, control logic, and current-sense amplifier - requires low-impedance layout |
| 7 OUT | High-current gate driver output | Drives external MOSFET with 300 mA sink/source capability and <190 ns rise/fall times |
| 8 VCC | Internal supply input | Accepts 9–21 V DC; powers all internal circuits and gate driver - bypass capacitor mandatory |
Key Features
| Feature | Design Value |
|---|---|
| Primary-side constant-current regulation | Eliminates opto-coupler, TL431, and secondary feedback components - reduces bill-of-materials and layout complexity |
| Integrated dimmer interface | Dual-pin (PD/DIM) analog sensing enables seamless leading-edge dimmer compatibility without external ADC or MCU |
| Acceleration start control | Reduces startup time by dynamically adjusting peak current until FB reaches 1.4–2.2 V threshold - avoids flicker at turn-on |
| Built-in protection suite | Hardware-level responses for LED open/short, overtemperature (+150°C), overcurrent (CS >4 V), and VCC OVP (32 V typ) |
| Lead-free & green packaging | SO-8 package meets RoHS 3 (2015/863/EU), contains <900 ppm Br/Cl and <1000 ppm Sb - compliant for eco-sensitive markets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar primary-side dimmable LED controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP1694AS-13 | Successor IC with enhanced dimmer compatibility, lower start-up current (≤50 µA), and extended VCC range (8–24 V) | Supports deeper dimming range (0.5–100%) and improved EMI performance in new designs | Preferred for new designs requiring higher reliability and broader dimmer interoperability |
| BP5609D | Non-isolated PSR controller with fixed 30 kHz frequency; lacks PD/DIM dual-sense architecture | Limited to non-dimming or PWM-dimming systems; no native TRIAC phase detection | Only suitable where phase-cut dimming is not required and cost is prioritized over dimmer flexibility |
Compared with AP1694AS-13, AP1690MTR-G1 offers proven field reliability but narrower dimming range and higher start-up current; versus BP5609D, it provides true primary-side dimming capability at the cost of slightly higher BOM count and layout sensitivity.

FAQ
What dimmer types does AP1690MTR-G1 support?
The AP1690MTR-G1 natively supports leading-edge (TRIAC) dimmers via its PD and DIM pins, which detect phase-cut waveform conduction angle and average input voltage. It does not support trailing-edge (ELV) or digital (DALI, 0–10 V) dimming without external interface circuitry. Compatibility has been validated across major residential dimmer brands including Lutron and Leviton.
Can AP1690MTR-G1 be used in isolated vs. non-isolated topologies?
Yes - the AP1690MTR-G1 is designed for both isolated flyback and non-isolated buck-boost topologies. Its primary-side regulation architecture eliminates the need for secondary feedback regardless of isolation, and the datasheet includes verified reference designs for both configurations with full safety and EMI compliance data.
How does the acceleration start function improve system behavior?
Acceleration start dynamically increases peak primary current during initial startup until the FB pin voltage reaches 1.4–2.2 V, reducing time-to-steady-state by up to 60%. This prevents visible LED flicker or pop-on artifacts common in PSR controllers and ensures reliable ignition even with high-output-capacitance LED strings.
What is the recommended minimum VCC bypass capacitance?
A minimum 10 µF low-ESR electrolytic or tantalum capacitor is required between VCC and GND, placed within 5 mm of the IC. This ensures stable gate drive during transient load steps and prevents UVLO dropout during MOSFET switching transitions, especially under low-line conditions where VCC ripple is highest.
