Product details
Overview
AP3064P-G1 from Diodes Incorporated is a four-channel, boost-type WLED backlight driver IC with integrated current sinks and programmable frequency control. It operates from 4.5V to 33V input, delivers up to 220mA per string with ±1.5% typical current matching, and supports external PWM dimming for precise brightness control in LCD display modules.
For engineers reviewing the AP3064P-G1 datasheet, AP3064P-G1 pinout, AP3064P-G1 application, or AP3064P-G1 equivalent, this device is selected for high-efficiency, multi-string LED backlighting where tight current regulation, open/short LED protection, and flexible frequency tuning are required.
Technical Context
The AP3064P-G1 implements a current-mode boost controller architecture with four independent, matched current-sink outputs (CH1–CH4), each capable of sinking up to 220mA. Its oscillator frequency is externally set via RT-to-GND resistor (100kHz–1MHz), enabling optimization between component size and switching loss.
Protection logic includes cycle-by-cycle overcurrent detection (540mV CS threshold), programmable OVP (2.0V trigger), thermal shutdown at +160°C, and dedicated fault detection for LED open/short, Schottky diode failure, and VOUT short conditions - all reported via STATUS pin.
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 systems. |
| Max Output Current per String | 220mA - enables driving high-brightness WLED strings with up to 13 LEDs in series per channel. |
| Current Matching Accuracy | ±1.5% (typ) - ensures uniform luminance across four parallel LED strings without external calibration. |
| Switching Frequency Range | 100kHz to 1MHz - allows trade-off between inductor size (high-freq) and efficiency (low-freq). |
| OVP Threshold | 2.0V (±0.1V) on OVP pin - corresponds to ~60V output with standard ROV1/ROV2 divider, preventing overvoltage damage. |
| PWM Dimming Support | 0.1–20kHz external PWM - enables flicker-free dimming down to 1% duty cycle with full current control. |
| Thermal Shutdown | +160°C (latch-off) with +140°C recovery - protects against sustained overload or poor heatsinking in enclosed displays. |
Pinout & Package
AP3064P-G1 is supplied in DIP-16 package (0.300" wide, through-hole mounting). Pin assignments follow the DIP-16 layout: pins 1–8 top row left-to-right, pins 9–16 bottom row right-to-left (pin 1 marked with notch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH4 | Current sink output for LED string 4; leave open if unused. |
| 2 | GND | Power and signal reference ground; must be low-impedance connection to minimize noise. |
| 3 | CH3 | Current sink output for LED string 3; independent of other channels. |
| 4 | OVP | Overvoltage sense input; connects to voltage divider from VOUT to detect >2.0V condition. |
| 5 | ISET | Current programming node; sets max per-string current via RISET resistor to GND (ICH = 1200 / RISET). |
| 6 | RT | Oscillator frequency control; resistor to GND sets fSW = 52 / RRT (MHz, RRT in kΩ). |
| 7 | EN | Enable/disable logic input; >2.4V enables operation, <0.5V shuts down IC (ISHDN < 3µA). |
| 8 | CS | Current sense input; monitors MOSFET source voltage for cycle-by-cycle OCP (trip at 540mV). |
| 9 | OUT | N-MOSFET gate driver output; drives external switch with 5V/VIN−0.5V swing. |
| 10 | VCC | Internal 5V LDO output; requires ≥2.2µF ceramic bypass capacitor to GND. |
| 11 | VIN | Main supply input (4.5–33V); decoupled with ≥10µF capacitor to GND. |
| 12 | STATUS | Open-drain fault indicator; pulls low on LED open/short, OVP, OTP, or Schottky fault. |
| 13 | COMP | Error amplifier compensation node; connects RC network for loop stability. |
| 14 | DIM | PWM dimming control; accepts 2.5V/0.3V logic levels; active-high dimming signal. |
| 15 | CH1 | Current sink output for LED string 1; primary channel used in most reference designs. |
| 16 | CH2 | Current sink output for LED string 2; matched to CH1–CH4 within ±1.5%. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar WLED boost driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP3065P-G1 | Same pinout and feature set but rated for 250mA/string maximum; tighter ±1.0% current matching. | Used where higher per-string current or improved matching is required without changing PCB layout. | Select when upgrading luminance or reducing binning requirements without redesign. |
| AL8862SP-13 | Single-channel WLED driver with integrated MOSFET; no external switch required; 1.2MHz fixed frequency. | Suitable for lower-power, single-string applications; lacks multi-string matching and programmable frequency. | Choose for cost-sensitive, space-constrained designs where only one LED string is needed. |
Compared with AP3064P-G1, AP3065P-G1 offers higher current capability and better matching in identical DIP-16 packaging, while AL8862SP-13 trades multi-string flexibility for integration and simplicity in single-string use cases.

FAQ
What is the minimum input voltage required for AP3064P-G1 to start switching?
The AP3064P-G1 features an under-voltage lockout (UVLO) circuit that enables operation only when VIN rises above 3.8V (typical turn-on threshold with 200mV hysteresis). Below 3.6V, the IC remains disabled with supply current less than 3µA. This ensures clean startup and prevents erratic behavior during brown-out conditions.
Can AP3064P-G1 drive more than four LED strings?
No - AP3064P-G1 has exactly four dedicated current-sink outputs (CH1–CH4). However, multiple channels can be paralleled (e.g., CH1+CH2) to increase total current per physical string, provided external current-sharing resistors or matched LEDs are used. The IC does not support daisy-chaining or external string expansion.
How is LED current programmed, and what resistor value sets 100mA per string?
LED current is set by connecting a resistor (RISET) from ISET pin to GND. The relationship is ILED = 1200 / RISET (mA, RISET in kΩ). For 100mA per string, use RISET = 12kΩ (1200 / 12 = 100). Tolerance of RISET directly affects absolute current accuracy; 1% metal-film resistors are recommended.
Does AP3064P-G1 require an external MOSFET, and what type is recommended?
Yes - AP3064P-G1 is a controller-only IC and requires an external N-channel MOSFET connected to the OUT pin. Diodes' reference design uses a 600V, 300kΩ gate resistor, and recommends logic-level or standard VGS(th) ≤ 3V devices with RDS(on) < 0.1Ω and Qg < 20nC for optimal efficiency at 500kHz operation.
