Lumissil Microsystems provides a wide selection of LED drivers designed to meet the requirements of various lighting projects. This article will focus on the 9-channel (9ch) and 18-channel (18ch) LED drivers and cover how lighting designers and engineers can select the appropriate LED driver for their projects. Key consideration factors are LED current, dimming, color accuracy, and EMI reduction capabilities. Additionally, this article will delve into the technical features of these 9 and 18-channel drivers

This article introduces two 32-bit Multi-Core Families that expand on Lumissil's Multiprocessor (MPU) portfolio: the X1600 and X2000. These MPUs utilize XBurst, a family of MIPS processors with (FPU) Floating Point Unit, dedicated security processor and use a System-in-Package (SIP) architecture to house memory. These features facilitate complex DSP computations, enable authentication, perform encryption/decryption and manage data storage. By integrating these features, the need for costly licenses is eliminated, simplifying design and reducing the BOM cost typically associated with competing in-class MPUs.

LED lighting has become a popular method for displaying device operational status. It is relatively simple to individually drive several LEDs. However, as the number of LEDs increases, the number of I/O hardware pins required to individually operate these LEDs grows to an unmanageable level. Driving large numbers of LEDs requires the use of a scanning matrix architecture.

Automakers try to differentiate their infotainment human-machine interface (HMI) displays and catch up to the technological advances now common in smartphones, tablets, and television displays. A local-dimming backlight technology is a direct-lit architecture where the LEDs are directly behind the LCD panel, as shown in Figure 1. Each LED or zone of LEDs can dim individually to illuminate only those pixels of the display needed by dynamically adapting to the image content on the display.

The IS32PM342X family consists of high-efficiency synchronous step-down voltage regulators designed for both industrial and automotive applications. These devices support an input voltage range of 3.8V to 36V and provide up to 4A of output current, with adjustable output voltages from 1V to 24V. The IS32PM342X family is ideal for high-efficiency applications where performance, reliability, and space are critical. These devices feature high efficiency (up to 93% at full load), protection mechanisms, and support for both FCCM and PFM operational modes to optimize performance across varying load conditions. The IS32PM342X family is ideal for power-conscious applications where longer battery life, high efficiency and small footprint, are critical, making them perfect for energy-saving markets such as the Internet of Things (IoT), wearables, and battery-operated devices. The IS32PM342X family is available in compact WFCQFN-14 and SOP-8-EP packages and includes integrated features such as spread spectrum frequency modulation and internal soft-start, making them perfect for space-constrained and high-reliability applications.
