Overview

The ILD8150XUMA1 is a high-performance 80V DC-DC buck LED driver IC designed to deliver up to 1.5A of output current. It utilizes a hysteretic current control scheme and integrates an 80V high-side MOSFET to simplify circuit design while providing flicker-free dimming down to 0.5 percent. This regulator is specifically optimized for high-power LED applications requiring wide input voltage ranges and precise hybrid dimming control.

Why Choose This Part

The IC features an integrated high-side switch that reduces external component count and PCB footprint in 8-pin DSO packages. It offers excellent dimming performance with a hybrid dimming mechanism that avoids flicker, while the wide 8V to 80V input range provides significant headroom for various power supply topologies.

Applications

Professional LED Lighting
Ideal for electronic control gear in commercial and industrial luminaires requiring high current and efficiency.
Smart Home Lighting
Supports deep dimming levels down to 0.5 percent for mood lighting and connected home applications.
Street and Area Lighting
The 80V rating and high efficiency make it suitable for outdoor LED systems powered by high-voltage rails.
Emergency Lighting
Reliable operation across a wide temperature range up to 150C with integrated thermal and over-current protection.

Getting Started

To evaluate the ILD8150, engineers can utilize the EVAL_ILD8150_DC_1.5A evaluation board which demonstrates the 1.5A buck configuration. Design documentation includes reference circuits for hysteretic control and guidance on selecting the external inductor and sense resistor for specific output current targets. Ensure the PG-DSO-8 package thermal pad is properly soldered to a copper plane to handle the 1.5A load heat dissipation.
