Product details
Overview
AP1695MTR-G1 from Diodes Incorporated is a discontinued high-efficiency, offline AC/DC LED driver IC with integrated 500V/2A MOSFET, operating in Boundary Conduction Mode (BCM) to achieve PF > 0.9 and THD < 30%. It delivers accurate constant-current regulation for dimmable LED lighting up to 10W without optocoupler or secondary feedback, and supports leading/trailing-edge dimmers with NEMA SSL6-compliant dimming down to 1%.
For engineers reviewing the AP1695MTR-G1 datasheet, AP1695MTR-G1 pinout, AP1695MTR-G1 application, or AP1695MTR-G1 equivalent, key selection considerations include its internal MOSFET rating (500V VBR(DS), 2.5A ID), valley-switching control, SO-7 package thermal resistance (θJA = 160°C/W), and built-in protections including UVLO, OVP, OTP, and output short/open detection.
Technical Context
The AP1695 implements constant-on-time (COT) PFM control in BCM to maintain high power factor across input voltage and dimmer phase angles. Its valley-switching detection uses FB pin sensing of auxiliary winding voltage to minimize turn-on loss, while internal current-sense comparator (VCS_REF = 1V) enables precise LED current regulation independent of line voltage.
Protection logic integrates multiple latched and hiccup-mode responses: VCC OVP (27–31V) and FB OVP (4.5–7.5V) trigger discharge-and-restart cycles; overtemperature shutdown activates at +150°C with +20°C hysteresis; and output short events force UVLO-based hiccup operation unless external fast-start circuitry is present.

Pinout & Package
AP1695MTR-G1 is housed in a 7-pin SOIC (SO-7) package with exposed pad for thermal enhancement, rated for -40°C to +105°C ambient operation. Pin 1 (S) connects to internal MOSFET source; Pin 7 (Drain) carries high-voltage switching node; Pin 4 (GND) serves as power and signal reference.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dimmable LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP1695-20C | Direct replacement with updated internal trimming; identical pinout, SO-7 package, and functional spec | Same dimmer compatibility, NEMA SSL6 compliance, and 10W capability; supports same buck/flyback topologies | Select for new designs-Diodes explicitly designates this as the active replacement for AP1695MTR-G1 |
| BP57722 | Non-integrated controller (external MOSFET required); higher max output power (18W); no valley switching | Better suited for higher-power commercial fixtures; lacks native 1% dimming depth and NEMA SSL6 certification | Choose when >10W output or discrete MOSFET selection (e.g., SiC) is required; not drop-in compatible |
Compared with AP1695-20C, the AP1695MTR-G1 shares identical functionality but lacks updated production trimming; compared with BP57722, it trades higher integration and tighter dimming control for lower maximum power and fixed MOSFET characteristics.

FAQ
Is AP1695MTR-G1 still in active production?
No-AP1695MTR-G1 is officially obsolete per Diodes Incorporated's datasheet (DS37312 Rev. 2-4). The manufacturer directs users to migrate to AP1695-20C, which maintains identical pinout, electrical specs, and SO-7 packaging while incorporating updated internal calibration for improved production yield and consistency.
Can AP1695MTR-G1 be used in flyback topology?
Yes-the AP1695 supports flyback configuration per its typical application circuit (page 3 of DS37312), using FB pin feedback from auxiliary winding for output voltage sensing and valley detection. However, its internal 2.5A MOSFET limits practical flyback output to ≤10W, and transformer design must ensure proper VCC winding regulation across load and line conditions.
What is the minimum recommended value for R1 (RI pin resistor)?
The datasheet specifies R1 ≤ 1.25 × 10⁶ Ω to avoid overshoot during startup. For optimal dimming performance in phase-cut applications, a lower value (e.g., 470 kΩ) is preferred-this reduces initial on-time and improves responsiveness to dimmer conduction angle changes, provided system stability is verified under worst-case line and temperature conditions.
Does AP1695MTR-G1 require external loop compensation?
No-AP1695MTR-G1 eliminates external loop compensation components by embedding stable internal control architecture. Its constant-on-time PFM modulation and valley-switching mechanism inherently maintain regulation stability across line, load, and temperature without requiring external RC networks or Type II/III compensators typically needed in voltage-mode or current-mode controllers.
