LX27906ID

Introduction

LX27906ID is a power management integrated circuit (PMIC) and LED driver, specifically designed for automotive use. The LX27906ID combines the functionalities of a power management integrated circuit (PMIC) and a LED driver, allowing it to be used in automotive lighting, interior lighting and instrument panel applications. The LX27906ID is a small form factor IC, with a footprint of only 2.20mm x 2.20mm, and can dissipate up to 2.0 Watts of power depending on the chosen application. The LX27906ID supports up to 4 parallel connected LEDs, is capable of controlling the brightness and colour of each LED independently, and is provided with a built-in error detector to detect if the LEDs have failed.

Application Field

The LX27906ID is a power management IC (PMIC) and LED driver specifically designed for automotive use. It can be used in a variety of applications including automotive lighting, interior lighting and instrument panel applications. In automotive lighting applications, the LX27906ID can be used to control the brightness and colour of the vehicle’s headlights, taillights and interior lighting. Additionally, the LX27906ID can also be used in instrument panel applications, to control the brightness and colour of the instrument panel backlighting. The LX27906ID is also compatible with automotive safety systems, and can therefore be used in applications where safety is important such as brake lights or reversing lights.

Key Features

• Small form factor of only 2.20mm x 2.20mm
• Supports up to 4 parallel connected LEDs
• Independent brightness and color control
• Built-in error detector
• Up to 2.0 Watts of power dissipation

Working Principle

The LX27906ID utilizes a switched-mode power supply (SMPS) topology, which consists of a switch mode regulator, driver, and control circuitry. The switch mode regulator is used to generate the required DC power for the LED. This is accomplished by switching the supply voltage on and off at a high frequency, in order to convert energy from the input voltage to desirable voltage levels for LED driver. This switching is controlled by the control circuitry on the LX27906ID, and is used to adjust the LED’s brightness and colour. The LX27906ID also includes error detect circuitry, which is used to detect if any of the LEDs have failed.
