Product details
Overview
AP3064AMTR-G1 from Diodes Incorporated is a four-channel WLED boost controller with integrated current sinks for LCD backlight driving. It operates from 4.5V to 33V input, delivers up to 220mA per string with ±1.5% typical current matching, and supports adjustable switching frequency from 100kHz to 1MHz. Used in LCD monitor and TV backlight systems requiring precise multi-string current regulation and robust fault protection.
For engineers reviewing the AP3064AMTR-G1 datasheet, AP3064AMTR-G1 pinout, AP3064AMTR-G1 application, or AP3064AMTR-G1 equivalent, key selection criteria include programmable LED current via ISET resistor, OVP threshold at 2.0V, thermal shutdown at +160°C, and support for external PWM dimming up to 20kHz.
Technical Context
The AP3064AMTR-G1 implements a current-mode boost controller architecture with four independent current-sink channels (CH1–CH4), each capable of sinking up to 220mA. Its internal 5V LDO powers the control circuitry, while the OUT pin drives an external N-MOSFET switch.
Protection logic includes cycle-by-cycle overcurrent detection (540mV CS threshold), programmable OVP (2.0V trigger, 250mV hysteresis), LED open/short detection (7.3V short threshold), and thermal shutdown (+160°C trip, +140°C recovery). STATUS pin asserts low during any active fault condition.
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 28V systems. |
| Max Output Current per String | 220mA - enables driving high-brightness WLED strings with up to 13-series LEDs per string. |
| Current Matching Accuracy | ±1.5% (typ) - ensures uniform brightness across all four backlight strings without manual calibration. |
| Switching Frequency Range | 100kHz to 1MHz - allows trade-off between inductor size (high-freq) and conduction loss (low-freq). |
| OVP Threshold | 2.0V (±0.1V) - sets output overvoltage limit via external resistor divider on OVP pin. |
| Thermal Shutdown | +160°C (trip), +140°C (recovery) - provides latch-off protection against sustained overheating. |
| PWM Dimming Frequency | 100Hz to 20kHz - supports flicker-free dimming down to 1% duty cycle with external signal. |
| UVLO Threshold | 3.8V (rising), 3.6V (falling) - prevents erratic startup or operation during brownout conditions. |
Pinout & Package
AP3064AMTR-G1 is packaged in SOIC-16 (3.9mm × 9.9mm, 1.27mm pitch), RoHS-compliant and green halogen-free. Pin functions are identical across SOIC-16, PSOP-16, DIP-16, and QFN-4×4-16 variants; this part uses the SOIC-16 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CH1–CH4 | LED current sink outputs | Four independent high-side current sinks; each can be disabled by leaving pin open. |
| ISET | Current reference setting | Connects to GND via resistor to set max per-string current (e.g., 12kΩ = 100mA). |
| OVP | Overvoltage sense input | Monitors output voltage via resistor divider; triggers shutdown if >2.0V. |
| RT | Frequency programming | Resistor to GND sets switching frequency (e.g., 100kΩ ≈ 520kHz). |
| EN | Enable control | Logic-high (>2.4V) enables IC; logic-low (<0.5V) reduces supply current to <3µA. |
| CS | Current sense input | Inputs MOSFET source voltage; triggers OCP at 540mV threshold. |
| OUT | Gate driver output | Drives external N-MOSFET gate with 5V/VIN−0.5V swing; supports fast rise/fall times (≤50ns). |
| VCC | Internal LDO output | 5V regulated supply for internal circuitry; requires ≥2.2µF ceramic bypass to GND. |
| VIN | Main power input | Accepts 4.5–33V; requires local 10µF ceramic capacitor for stability. |
| STATUS | Fault status indicator | Open-drain output pulled low during OVP, OTP, LED open/short, or Schottky fault. |
| COMP | Error amplifier compensation | Connects Type-II compensation network to stabilize current-loop response. |
| DIM | PWM dimming input | Accepts 2.5V/0.3V logic-level PWM; modulates all enabled strings simultaneously. |
| GND | Power and signal ground | Common return for VIN, ISET, RT, CS, and DIM; must be low-impedance connection. |
Key Features
| Feature | Design Value |
|---|---|
| Four independent current sinks | Enables simultaneous, matched-current drive of up to four WLED strings without external current mirrors. |
| Programmable OVP with hysteresis | 2.0V trigger with 250mV hysteresis prevents oscillation during transient overvoltage events. |
| Integrated LED open/short protection | Automatically disables faulty string while maintaining operation of remaining strings; no external sensing required. |
| VOUT short / Schottky diode open detection | Monitors OVP pin voltage <0.1V to detect output short or diode failure, disabling gate drive immediately. |
| Soft-start with programmable ramp | Controlled via COMP pin capacitor; prevents inrush current and output overshoot during startup. |
| Schottky/inductor short-circuit protection | Latches off after 16 cycles if CS voltage exceeds 800mV, protecting MOSFET and inductor under hard fault. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar WLED boost controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL8862Q-13 | Single-channel, 150mA max, fixed 500kHz frequency, no OVP pin - uses internal reference. | Lacks multi-string capability and programmable OVP; suited only for simpler single-string designs. | Select when cost-sensitive single-string backlighting suffices and board space permits discrete current-setting components. |
| LM3409QMY/NOPB | Single-channel, 3A max, external MOSFET driver, no integrated current sinks - requires external sense resistors. | Requires four separate ICs + layout for quad-string operation; lacks built-in LED open/short protection. | Choose only if higher peak current (>220mA) per string or custom topology (e.g., SEPIC) is required. |
Compared with AL8862Q-13 and LM3409QMY/NOPB, AP3064AMTR-G1 uniquely integrates four matched current sinks, programmable OVP, and comprehensive fault detection in one SOIC-16 package-reducing BOM count, PCB area, and validation effort for multi-string LCD backlight designs.

FAQ
What is the minimum recommended ISET resistor value for AP3064AMTR-G1?
The minimum recommended ISET resistor is 5.6kΩ, corresponding to ~214mA per string (per ILED = 1200 mA × kΩ / RISET). Using lower resistance risks exceeding absolute maximum channel current ratings and degrading current matching accuracy due to internal reference limitations.
Can AP3064AMTR-G1 drive more than four LED strings?
No - AP3064AMTR-G1 has exactly four dedicated current-sink outputs (CH1–CH4). To drive additional strings, multiple AP3064 units must be synchronized using shared RT and DIM signals, or a higher-channel-count driver like the AP3065 (6-channel) should be selected.
How does the STATUS pin behave during normal operation?
During normal operation with no faults, STATUS remains in high-impedance (open-drain) state and must be pulled up externally (typically 10kΩ to VCC). It actively pulls low only when detecting LED open/short, OVP, OTP, VOUT short, or Schottky diode failure - serving as a unified fault flag.
Is external compensation required on the COMP pin?
Yes - COMP requires an external Type-II compensation network (resistor + capacitor + optional capacitor) to stabilize the current-loop feedback. The datasheet recommends starting with 10kΩ + 1nF + 100pF; values must be tuned based on output capacitance, inductance, and target phase margin.
