Overview

Each LED string in an LED strip needs a linear LED driver IC for up to 100 mA LED current. Therefore, applications using linear LED driver ICs need an IC with low voltage overhead so as many LEDs as possible can be stacked in series. Doing so increases the efficiency and reduces the thermal overload. Check out our portfolio below for more information.

About Infineon solutions for LED strips and signage

When designing your LED strips, consider Infineon's portfolio of high-quality, cost-efficient components. Our family of barrel connector replacement (BCR) LED drivers contains the smallest and most-affordable products for linear LED driver ICs. At the same time, applications using linear LED driver ICs need a low voltage overhead of the IC so as many LEDs as possible can be stacked in series. This increases efficiency and reduces thermal overload on the LED board, which are features that the market demands.

Explore our products, reference designs, and demo boards below for more details on how you can maximize LED strips and signage designs with Infineon.

Linear LED driver ICs

The linear LED drivers of the BCR family are perfectly suited for driving LED currents from 10 mA to 250 mA, making them the ideal choice for low- to mid-power LEDs in general lighting applications. These drivers represent the lowest-cost solution that requires a low external part count and PCB space. The light output can be adjusted via an external resistor. Thanks to its negative thermal coefficient, the LED load will be protected from overheating. The new-generation BCR430U and BCR431U drivers feature an extra-low voltage drop and a smart temperature controlling circuit.

Cost-effective LED driver ICs

Other members of the BCR family, the BCR401W and BCR402W drivers, offer the most cost-effective solution for driving LED lighting. These drivers feature up to 500 mW power dissipation in a small SOT-343 package and a negative thermal coefficient that reduces output current at higher temperatures. They are also suitable for a wide variety of applications and power ranges and have an output current up to 60 mA, adjustable by a resistor.

All of these features add up to exciting benefits, such as constant driving current control for homogeneous light output, longer lifetime of the LEDs due to reduced output current at higher temperatures (negative thermal coefficient), and easy paralleling of drivers to increase current. They also enable stacking of LEDs in front of the driver to increase input voltage and can contribute to longevity and reliability of the LED system overall.

Low voltage drop LED driver ICs

Our BCR430U and BCR431U solutions are the perfect choice for low voltage drop LED lighting drivers. These members of the BCR family feature a maximum 200 mV voltage drop in the driver stage, a supply voltage range from 6 to 42 V, and smart overtemperature protection. Additionally, BCR430U can control up to 100 mA LED current, while BCR431U can control up to 42 mA LED current.

Utilizing very low voltage drop drivers allows for the use of more LEDs or longer strips overall, which means fewer feeding points, flexible current setting via resistors, and homogeneous light output. One additional benefit is the integrated overtemperature protection (OTP), which not only extends the lifetime of the IC but also can be used to protect the reliability of the LED strip.

Robust LED driver ICs

The BCR family also includes a large selection of extremely robust LED lighting drivers for strips and signage. Some family members to consider are BCR320U and BCR420U. These LED drivers deliver features such as homogeneous light output in different LED strings regardless of the Vf and supply voltage, and are easy to implement with a low component count. 

Additionally, these products offer the flexibility to adjust the current via an external resistor, from 10 mA up to 250 mA. Benefits include a direct microcontroller interface for PWM dimming for BCR421U and BCR321U or dimming via PWM power, a negative thermal coefficient to protect the lifetime of LEDs, and a high power dissipation capability.

The other members of the robust portion of the family are the BCR401U, BCR402U, and BCR405U. These feature LED drive currents that are preset to 10/20/50 mA, output currents that are adjustable by resistors up to 65 mA, a supply voltage up to 40 V, and high-side current control.

LED driver ICs for 48 V supply

BCR602 60 V linear LED controller IC is another member of the BCR family, offering flexible dimming. Specifically, it includes pure analog dimming down to 3%, and PWM dimming down to 1%. Additional features include VS from 8 V to 60 V, current precision of ±3%, and overtemperature protection.

Benefits afforded by BCR602's features include flicker-free deep dimming performance, good light quality enabled by constant control of the current, and OTP that protects the LEDs and the system. Additionally, since operating in safety extra low voltage (SELV) area is enabled, flexible designs with BJTs or N-channel MOSFETs can be implemented.
