AP3064MTR-G1 LED Driver is an innovative product designed to offer a broad range of output current options and excellent temperature performances. It is a member of the PMIC - LED Drivers family, specially designed to address the needs of light-emitting diode (LED) illuminated systems.

AP3064MTR-G1 features high power efficiency, excellent temperature performance and low power consumption. Its output current is adjustable, so it can fit a variety of LED application fields. Moreover, the power-on delay and current mode are optimized to accurately control LED dimming.

AP3064MTR-G1 LED Driver is suitable for LED illumination and smart lighting. It is also widely used in automotive lighting, single color LED strips and modules, and various display systems.

AP3064MTR-G1 LED Driver adopted a wide range of working voltages covering from 6 V to 30 V, and the output current can be adjusted from 10 mA to 1000 mA. It is available in a small SOT26 6-pin package, which allows for a small PCB size, low component height and high flexibility in design.

AP3064MTR-G1 offers a wide range of protections, such as short circuit protection, over-current protection, over-temperature protection and over-voltage protection. It is certified according to UL Class 2, so it can satisfy most safety requirements.

The working principle of the AP3064MTR-G1 LED Driver is based on a current-mode approach. The maximum output current (I-Max) is controlled by an internal control voltage (Vref) generated by an internal current source connected to the FB pin. The LED current is monitored and compared to I-Max. If the LED current exceeds I-Max, the PWM signal is generated, and the LED current is decreased to I-Max level. If the LED current is below I-Max, PWM signal is suppressed until the LED current reaches I-Max again.

The dimming control is realized by Pulse Width Modulation (PWM) of the internally generated voltage reference (Vref). The high and low value of the Vref control the peak and valley of the output current respectively. That is, by changing Vref accordingly, the ratio of the two currents (Peak/Valley) can be adjusted, so the PWM dimming of the LED brightness can be realized.

In summary, AP3064MTR-G1 LED Driver is an advanced product that supports dynamic current modification and accurate dimming control. It is used in a wide range of LED application fields and is suitable for LED illumination and smart lighting, automotive lighting, single color LED strips and modules, and various display systems.
