LM3401MMX/NOPB is a highly integrated LED driver and ballast control with control and protection. It is used in applications requiring highly efficient LED lighting and LED backlighting with low cost and an optimized solution. It is a part of PMIC – LED Drivers and is ideal for LED applications requiring a high level of control and protection.

The LM3401MMX/NOPB device provides a low cost solution for systems requiring a low power, non-isolated, average current-mode LED driver with internal dimming and active bridgeless PFC control. It offers flexibility for both single-stage and two-stage LED designs. This device includes an LED driver side, featuring a 40-V n-channel MOSFET, an LED dimming side, featuring an LED dimmer control circuit, a current control side, featuring an internal active switch, and a line side, featuring an external PFC detection circuit. The internal LED driver can be used to provide adjustable and constant current-regulated LED drive capability.

LM3401MMX/NOPB integrates a high-side MOSFET switch and a dimming control circuit. The MOSFET switch is used to drive the LED current and is capable of delivering up to 1 A of continuous current. The dimmer control circuit consists of a dimmer control interface, a reference voltage regulator, and a power supply. It is used to control the brightness of the LEDs by controlling the duty cycle of the MOSFET switch. The control loop bandwidth and oscillator frequency can be adjusted to suit a variety of application requirements.

In addition to the integrated driver and dimmer circuitry, the LM3401MMX/NOPB includes protection features such as under voltage lockout (UVLO), overvoltage protection (OVP), short circuit protection (SCP), and thermal shutdown (TSD). This device also features an accurate active PFC control circuit, which allows the system to maintain a high level of power factor. This ensures that energy is used efficiently.

The LM3401MMX/NOPB is an ideal solution for applications requiring a reliable, low-cost and highly efficient driving solution. With its wide range of features and protection, it is the perfect choice for LED backlight, bulb and lamp applications.
