BCR421UE6327HTSA1 is a comprehensive power management integrated circuit (PMIC) designed specifically for LED drivers. This PMIC enables further development of efficient, effective, and reliable LED driver products. As a complete power management solution, the BCR421UE6327HTSA1 integrates a linear regulator (LDO), DC/DC converters, voltage aligners and much more.

Application Field

The BCR421UE6327HTSA1 offers a wide range of applications for LED drivers, such as entertainment and architectural lighting, automotive headlights, interior and exterior lighting, garden decoration and fountains. These modules serve many different purposes for different customers and industrial applications. It is also used for industrial lighting, such as in factories, offices, and stores, where the module helps to improve light quality, reduce power consumption, and enhance product quality.

Working Principle

The BCR421UE6327HTSA1 features an adjustable voltage aligner, DC/DC converter, linear regulator(LDO), and a wide input voltage range from 2.7V to 14V. It offers two different operating regimes: constant current and constant voltage. When operated in constant current mode, the unit will provide a precise output current for driving LEDs according to the programmed target.In constant voltage mode, the unit can be used to regulate the LED circuit output voltage accurately. While operating in either mode, the output current can range from 0mA to 320mA, depending on the input voltage.

The BCR421UE6327HTSA1 features six integrated LED drivers, each configured as a boost LED driver, buck LED driver, or power failover switch. It also features an adjustable dimming capability, allowing dimming ratios of between 0-100%. Its high efficiency ensures low power consumption and a small form factor.

In addition to its standard mode, the BCR421UE6327HTSA1 includes two special operating modes, namely discrete control and PWM control. The discrete control mode provides user-defined lighting states, such as ‘on’, ‘off’, ‘strobe’, and ‘blink’. The PWM mode provides a wide range of dimming possibilities, from fast flickering to dynamic lighting.

The BCR421UE6327HTSA1 meets all requirements for commercial grade LED drivers, such as high efficiency, easy integration and operation, and high reliability. This makes it the perfect choice for engineers and designers looking for a power management IC that meets their requirements.
