Overview

The A6264KLPTR-T is a low-cost, low-complexity, and efficient LED driver IC. It is designed for high brightness LED applications as well as for general purpose LED applications. It has an input voltage range of 4.5 to 28 V and can drive up to 4 LED channels up to 1.5A, providing an output current of up to 5A. It also offers a wide current range from 30mA to 1.5A, making it ideal for a wide range of LED applications. In addition, the device offers a range of features such as dimming control, over temperature protection, overtemperature protection, and short-circuit protection.

Features

• Can drive up to 4 LED channels up to 1.5A
• Input voltage range of 4.5V to 28V
• Wide current range from 30mA to 1.5A
• Dimming control, dimming pick point can be adjusted0-100%
• Over temperature protection and overtemperature protection
• Short-circuit protection

Working principle

The A6264KLPTR-T uses a constant current control to accurately control the current supplied to the LEDs. The current is switched on and off using a buck converter. In other words, it operates in a switched mode using a pulse width modulator (PWM). The input voltage is regulated by a PWM-controlled power switch. The voltage is also modulated between 0 and the peak voltage of the input voltage. The range of modulated voltage affects the output current. In other words, the higher the input voltage, the higher the output current.

The A6264KLPTR-T is programmed by means of a single control line. This feature allows users to easily adjust the brightness of the LEDs by means of a digital signal. The device also supports both analog and digital dimming. When the dimming line is pulled low, the device operates in PWM dimming mode. When the dimming line is pulled high, the device operates in analog dimming mode.

Applications

The A6264KLPTR-T is mainly used in high power LED related applications such as:

• LED Strip lights
• Street lights
• Flood lights
• Stage lights
• Factory lighting
• High bay lights
• Office lighting
• Retail lighting
• Automotive headlights and taillights.
