Product details
Overview
AP3064FNTR-G1 from Diodes Incorporated is a four-channel, boost-type WLED backlight driver IC with integrated 4-string current sinks, operating from 4.5V to 33V input and delivering up to 220mA per string with ±1.5% typical current matching. It features programmable switching frequency (100kHz–1MHz), external PWM dimming, and comprehensive protection including OVP, OTP, LED open/short, and Schottky diode fault detection. It targets LCD TV and monitor backlight systems requiring high channel uniformity and robust fault handling.
For engineers reviewing the AP3064FNTR-G1 datasheet, AP3064FNTR-G1 pinout, AP3064FNTR-G1 application, or AP3064FNTR-G1 equivalent, this page delivers verified technical context, QFN-4×4-16 package mapping, real-world dimming control behavior, and validated alternative options for WLED backlight designs.
Technical Context
The AP3064FNTR-G1 implements a fixed-frequency current-mode boost controller architecture with four independent, matched current-sink channels driven by a single external power MOSFET. Its internal 5V LDO powers gate drive and analog circuitry, while the RT pin sets oscillator frequency via an external resistor, enabling optimization between component size and efficiency.
Protection logic operates in priority order: UVLO and OVP disable switching first; then LED open/short, VOUT short/diode-open, and Schottky/inductor short conditions trigger latched shutdown or dynamic channel disable. STATUS pin asserts low on any active fault, and DIM accepts 100Hz–20kHz PWM signals for synchronized brightness control across all enabled strings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 33V - supports wide-range industrial and display power rails, including 12V, 24V, and 32V nominal supplies. |
| Max Output Current per String | 220mA - enables driving high-brightness WLED strings (e.g., 13-series LEDs at 120mA) without external current amplification. |
| Current Matching Accuracy | ±1.5% (typ) - ensures consistent luminance across four parallel backlight zones, critical for uniform LCD panel illumination. |
| Switching Frequency Range | 100kHz to 1MHz - allows trade-off between inductor size (high-freq) and conduction loss (low-freq) in compact or thermally constrained layouts. |
| OVP Threshold | 2.0V ±0.1V at OVP pin - corresponds to ~60V output with standard ROV1/ROV2 divider, preventing overvoltage damage during open-string events. |
| PWM Dimming Frequency Support | 0.1kHz to 20kHz - avoids audible noise while enabling fine-grained brightness control down to 1% duty cycle. |
| Thermal Shutdown Temp | +160°C (latch), +140°C (recovery) - provides fail-safe operation under sustained overload or poor heatsinking in enclosed displays. |
| Quiescent Current | 3µA (shutdown), 3–5mA (active) - minimizes standby power in always-on display subsystems. |
Pinout & Package
AP3064FNTR-G1 is housed in a RoHS-compliant, lead-free QFN-4×4-16 package with exposed thermal pad (EP). The 4mm × 4mm footprint supports high-density PCB layouts and efficient heat dissipation via soldered EP connection to internal ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EP) | Exposed Pad | Thermal and electrical ground connection; must be soldered to PCB copper for thermal management and noise immunity. |
| 1 | CH4 | Current sink output for LED string 4; left open if unused - no pull-up/pull-down required. |
| 2 | ISET | Reference current setting node; connects to GND via RISET to program max current (ICH = 1200 mA / RISET[kΩ]). |
| 3 | OVP | Voltage monitor input for output overvoltage protection; threshold is 2.0V with 250mV hysteresis. |
| 4 | RT | Oscillator frequency programming node; fOSC ≈ 52 MHz / RT[kΩ], enabling precise frequency selection. |
| 5 | EN | Enable control with 2.4V high-threshold and 0.5V low-threshold; draws <3µA in shutdown mode. |
| 6 | CS | Current sense input for cycle-by-cycle overcurrent protection; triggers at 540mV (OCP) or 800mV (Schottky/inductor short). |
| 7 | OUT | Gate drive output for external N-MOSFET; swings from 5V to VIN−0.5V with 30–50ns edge times. |
| 8 | VCC | 5V linear regulator output; requires ≥2.2µF ceramic bypass capacitor to GND for stable gate drive and internal bias. |
| 9 | VIN | Main supply input; requires 10µF bulk capacitance to GND to suppress ripple and support transient load demands. |
| 10 | STATUS | Open-drain fault indicator; pulls low on LED open, short, OVP, OTP, or VOUT short/diode-open events. |
| 11 | COMP | Error amplifier compensation node; connects to RC network for loop stability and soft-start timing control. |
| 12 | DIM | PWM dimming input; accepts logic-level signals (2.5V high, 0.3V low); disables dimming if tied high. |
| 13 | CH1 | Current sink output for LED string 1; identical function and specs to CH2–CH4. |
| 14 | CH2 | Current sink output for LED string 2; supports independent enable/disable per string via open-circuit configuration. |
| 15 | GND | Analog and power ground reference; must be connected to EP and system ground with low-impedance path. |
| 16 | CH3 | Current sink output for LED string 3; shares same current regulation accuracy and thermal derating as other channels. |
Key Features
| Feature | Design Value |
|---|---|
| Four independent current sinks | Enables simultaneous, uniform driving of four separate WLED backlight zones without external current mirrors or op-amps. |
| Programmable OVP with external divider | Allows safe adaptation to varying LED string counts (e.g., 8–20 LEDs) by adjusting ROV1/ROV2 ratio without IC change. |
| Integrated Schottky/inductor short protection | Detects >800mV on CS pin for >16 clock cycles, preventing MOSFET destruction during catastrophic diode or inductor failure. |
| VOUT short and Schottky diode open detection | Monitors OVP pin voltage <0.1V to disable switching - protects against output shorts and missing diodes before startup or during operation. |
| External PWM dimming with 1% resolution | Supports full brightness range using standard microcontroller PWM outputs, eliminating need for analog dimming DACs or filters. |
| Soft-start with COMP pin control | Prevents inrush current and output overshoot via externally adjustable ramp time, configurable with RC network on COMP. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar four-channel WLED boost driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL8863-7DT-13 | Single-channel, 1.5A max; requires external current-sharing resistors for multi-string use; no integrated OVP pin - relies on external comparator. | Suitable for lower-cost, lower-channel-count designs where layout space permits discrete current balancing. | Choose when only one high-current string is needed or when BOM cost outweighs design simplicity and matching precision. |
| LM3409QMY/NOPB | Single-channel, 1.25A boost controller; lacks integrated current sinks - needs external MOSFET + sense resistor per string; no STATUS pin. | Better suited for custom high-power LED arrays where flexibility in topology (buck-boost, SEPIC) is required over integrated simplicity. | Prefer when designing non-standard LED configurations or when thermal management allows discrete high-side sensing per string. |
Compared with AL8863-7DT-13 and LM3409QMY/NOPB, the AP3064FNTR-G1 delivers true four-channel integration with ±1.5% matching and unified fault reporting - reducing component count, PCB area, and validation effort for standard LCD backlight architectures.

FAQ
What is the minimum recommended input voltage for reliable startup?
The AP3064FNTR-G1 has a UVLO threshold of 3.6V (rising) with 200mV hysteresis, meaning it reliably starts up when VIN reaches 3.8V. However, stable operation requires VIN ≥4.5V per datasheet specifications - below this, VCC regulation degrades and current accuracy falls outside guaranteed limits. Always maintain ≥4.5V during normal operation.
Can CH1–CH4 be used independently with different current settings?
No - all four channels share the same ISET pin and therefore operate at identical programmed current. The datasheet confirms "the current of 4 strings are simply programmed from 20mA to 220mA with an external resistor" on ISET. Independent current control requires external per-string current sources or discrete drivers.
How does the STATUS pin behave during PWM dimming?
STATUS remains high during normal PWM dimming unless a fault occurs. It only pulls low during active protection events: LED open/short, OVP, OTP, VOUT short, or Schottky diode faults. Dimming transitions do not trigger STATUS - it reflects only safety-critical hardware faults, not operational modulation states.
Is the QFN-4×4-16 package thermally enhanced compared to SOIC-16?
Yes - the QFN-4×4-16 package has θJA = 55°C/W (free air), versus 100°C/W for SOIC-16. This 45% lower thermal resistance results from the exposed pad's direct thermal path to the PCB ground plane, making it significantly more suitable for high-current (≥150mA/string) or high-ambient-temperature applications where junction temperature must stay below +150°C.
