Diodes ZXLD1350ET5 30V LED Driver, Internal Switch, 350mA, SMD

The Diodes ZXLD1350ET5 LED Driver is a surface-mount LED driver with an adjustable output current of up to 350mA, designed for reliable and precise control of lighting systems.

Overview

The ZXLD1350ET5 integrates a hysteretic mode inductive step-down (buck) converter that operates from a wide input voltage range of 7V to 30V. It efficiently drives single or multiple series-connected LEDs, and its simple, low-parts-count design simplifies circuit implementation while maintaining high performance.

Key Features

• Integrated 30V NDMOS switch and internal PWM filter for a compact and robust solution
• Efficiency of up to 95%, ensuring minimal power loss and reduced thermal management requirements
• 40V transient capability for enhanced durability in demanding electrical environments
• Output current accuracy typically within 4% for consistent LED brightness
• Output current adjustable by DC voltage or PWM waveform, with a 100:1 PWM adjustment range
• Applying 0.2V or lower to the ADJ pin turns the output off and switches the device into a low-current standby state
• Qualified to the AEC-Q100 Grade 2 standard

Applications

The driver is suited to lighting systems using single or multiple series-connected LEDs, and its AEC-Q100 Grade 2 qualification makes it suitable for automotive and other high-reliability applications. Its surface-mount TSOT-23 package with five pins measures 33 mm wide, 43 mm high and 15 mm deep, and weighs 12 grams.
