Overview

Topology	Buck Converter
Input voltage	8-80 V
Output 1	1.5 A
IC revision	2.2

Description

The reference board REF_ILD8150E_HE shows how to enable headroom voltage control in LED drivers by combining an AC-DC flyback controller and a DC-DC buck converter, enhancing system performance and reducing design costs.

Features

DC/DC buck with hysteretic current regulation
Output current up to 1.5 A DC
Integrated 80 V high-side MOSFET switch with low RON
Hybrid dimming to 0.5% of the target current
Wide operating voltage range 8 V to 80 V
Cycle-by-cycle current limitation
Under-voltage lockout
Thermal protection
Flicker free operation
Digital soft-start
Pull-down transistor to avoid LED glowing

Typical applications

Electronic Control Gear (ECG) for LED luminaries
