Introducing the PAM2861CBRC from Diodes Incorporated

The PAM2861CBRC is a high-efficiency, constant-current, step-up DC/DC converter designed and manufactured by Diodes Incorporated, a leading global provider of discrete, logic, analog, and mixed-signal semiconductors. This innovative product is specifically engineered to meet the needs of power LED applications and is capable of driving up to 10 series-connected LEDs at a constant current for uniform brightness.

With its wide input voltage range of 0.9V to 18V, the PAM2861CBRC is versatile and can be powered from a variety of sources, including single-cell batteries, making it an ideal choice for portable and battery-operated devices. The device ensures a constant current output, adjustable up to 1.2A, which not only provides stable LED performance but also enhances the longevity of the LEDs by preventing overcurrent conditions.

The PAM2861CBRC incorporates a fixed PWM frequency of 1MHz which allows for the use of small external components, thereby reducing the overall footprint and cost of the solution. Additionally, the converter features an integrated soft-start function that minimizes inrush current during startup, contributing to the extension of battery life and the reliability of the system.

Efficiency is a key aspect of the PAM2861CBRC, with its ability to achieve up to 93% efficiency, thus minimizing power loss and heat generation. This high efficiency, combined with a thermal shutdown mechanism, ensures that the device operates safely under a wide range of conditions.

For design flexibility, the PAM2861CBRC offers both PWM and analog dimming control, supporting a broad range of brightness levels and enabling energy-saving strategies when full brightness is not required. This feature is particularly useful in applications where variable illumination is needed, such as backlighting, accent lighting, or flashlights.

The PAM2861CBRC comes in a compact TSOT25 package, making it suitable for space-constrained applications. With its robust design and comprehensive features, the PAM2861CBRC is a reliable and efficient solution for driving high-power LEDs in a diverse array of products.
