Product details
Overview
AP3190W6-7 from Diodes Incorporated is a primary-side regulated (PSR) AC/DC switching mode power supply controller in SOT26 (Type SM) package, designed for offline flyback converters without optocoupler feedback. It delivers 80%+ efficiency at 10% load, supports QR/AM/Burst multi-mode operation, and integrates VCC OVP, output OVP/SCP, and adjustable external OTP via NTC resistor - used in compact 5–20W adapters and smart speaker power supplies.
For engineers reviewing the AP3190W6-7 datasheet, AP3190W6-7 pinout, AP3190W6-7 application, or AP3190W6-7 equivalent, key selection criteria include no-load input power (<65mW), CV/CC dual-loop regulation accuracy (VFB = 2.74V ±4.2mV), QR valley detection capability, adjustable line compensation (RLINE_IC = 173Ω typ), and thermal shutdown thresholds (OTP shutdown at 0.5V, recovery at 0.75V).
Technical Context
The AP3190W6-7 implements primary-side regulation using auxiliary winding voltage sampling at the FB pin to derive output voltage and current without secondary-side feedback components. Its multi-mode control dynamically selects QR (valley-on), AM (fixed-frequency adaptive mode at 60kHz/80kHz), and burst mode based on load and line conditions.
It features integrated leading-edge blanking (275ns typ), programmable cable compensation (2.0% typ), and dual-stage OTP with hysteresis (0.5V shutdown / 0.75V recovery). The CS pin senses primary current with three threshold levels (VCS_H = 1100mV, VCS_M = 730mV, VCS_MAX_BURST = 560mV) to enable precise CC regulation across load ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| No-load Input Power | <65mW at high-line - enables Energy Star Level VI and CoC Tier 2 compliance in ultra-low standby designs. |
| Feedback Threshold Voltage | 2.74V ±4.2mV - sets ±0.15% CV regulation accuracy under full-load and temperature variation. |
| Current Sense Thresholds | VCS_H = 1100mV (CV heavy load), VCS_M = 730mV (CV light load), VCS_MAX_BURST = 560mV (burst mode limit). |
| Switching Frequency | 80kHz at low line / 60kHz at high line in AM2 mode - balances EMI, transformer size, and efficiency. |
| OTP Threshold | 0.5V shutdown / 0.75V recovery at OTP pin - enables precise thermal shutdown with 40°C hysteresis using external NTC. |
| Leading Edge Blanking | 275ns typ - prevents false current-sense trip during MOSFET turn-on spike, ensuring stable pulse-width control. |
| Output Drive Capability | ISOURCE_H = 27.7mA max - directly drives medium-power external MOSFETs without gate driver IC. |
Pinout & Package
SOT26 (Type SM) - 6-pin surface-mount package with 0.95mm pitch, 2.95mm × 1.65mm footprint, and 1.10mm height; moisture sensitivity level 3 per JESD22-A113.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OTP | External overtemperature protection input | 100µA current source pulls voltage down with NTC; triggers shutdown below 0.5V and recovers above 0.75V. |
| 2 - GND | Power and signal reference ground | Common return path for internal regulators, protection comparators, and CS/FB sensing circuits. |
| 3 - FB | Auxiliary winding feedback input | Samples reflected voltage for CV/CC regulation; also detects VDS valley for QR operation and provides SUVP/SCP fault detection. |
| 4 - VCC | Internal supply rail input | Accepts 5.8–25V; powers internal circuitry; includes 29–31V OVP clamp and startup regulator with 15V threshold. |
| 5 - OUT | Gate drive output | PWM output driving external N-channel MOSFET; 10.8mA min / 27.7mA max sink/source capability. |
| 6 - CS | Primary current sense input | Monitors voltage across current-sense resistor; controls MOSFET turn-off timing for precise peak-current limiting and CC regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Burst mode operation | Reduces switching losses at light/no load, enabling <65mW no-load input power and meeting global energy efficiency standards. |
| Primary-side regulation (PSR) | Eliminates optocoupler and TL431, reducing BOM cost and PCB area while maintaining ±3% CV/CC accuracy across line/load/temperature. |
| Multi-mode QR/AM control | Switches between quasi-resonant (valley-on), adaptive fixed-frequency (60/80kHz), and burst modes - optimizing EMI, efficiency, and audio noise simultaneously. |
| Adjustable line compensation | Compensates for primary current sensing error due to varying input line slope using RLINE_IC = 173Ω and FB-connected resistive network. |
| Integrated protections | Auto-recovery SCP (1.1V FB threshold, 27ms delay), VCC OVP (30V), FB SUVP (1.65V), OTP (external + internal), and CS fault detection - no external components required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar primary-side regulated flyback controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP6004DJ-LF-Z (Monolithic Power) | Higher VCC OVP (36V), lower no-load power (45mW), but requires external LEB and lacks built-in line compensation. | Preferred for ultra-low standby designs where board space allows discrete LEB and compensation networks. | Select when tighter no-load power target (<50mW) outweighs BOM simplification benefit of AP3190's integrated features. |
| LNK3206P (Power Integrations) | Integrated MOSFET (725V), higher integration, but fixed 66kHz frequency and no QR mode or adjustable OTP. | Suitable for cost-sensitive, low-component-count designs where QR EMI advantage is not critical. | Choose when system-level integration (MOSFET + controller) reduces total solution size more than PSR flexibility. |
Compared with MP6004DJ-LF-Z and LNK3206P, the AP3190W6-7 uniquely combines QR valley detection, programmable line compensation, and dual-threshold external OTP in a 6-pin SOT26 - enabling optimal trade-offs among EMI, efficiency, thermal safety, and BOM count in mid-power adapters.

FAQ
What is the purpose of the OTP pin on the AP3190W6-7?
The OTP pin accepts an external NTC thermistor to implement adjustable overtemperature protection. A 100µA internal current source develops a voltage inversely proportional to NTC resistance; shutdown occurs below 0.5V and recovery above 0.75V, providing 40°C hysteresis. During burst mode and startup, OTP is disabled to prevent false triggering.
How does the AP3190W6-7 achieve primary-side constant current regulation without secondary sensing?
It calculates output current by measuring primary peak current via the CS pin and correlating it with the off-time (tOFFS) and on-time (tONS) ratio using Equation 2 from the datasheet. The controller maintains VCS × tONS/(tONS + tOFFS) = VREF_CC (0.45V typ), enabling accurate CC regulation independent of secondary-side components.
Can the AP3190W6-7 operate in quasi-resonant mode across all input voltages and loads?
No - QR mode activates only at low-line (90–132VAC) and heavy-load conditions when tOFF approaches zero. At high line or light load, it transitions to AM2 (60/80kHz fixed frequency) or burst mode. Valley detection is performed via FB pin sampling, and QR operation is automatically disabled if valley detection fails.
What is the function of the RLINE_IC resistor in the AP3190W6-7 application circuit?
RLINE_IC (173Ω typ) sets the gain of the adjustable line compensation network connected to the FB pin. It counteracts primary current sensing error caused by varying dI/dt across input line voltages, ensuring consistent output current regulation (±3%) from 90VAC to 264VAC without secondary feedback trimming.
