MIC2287-24BML-TR

LED Driver IC Overview

The MIC2287-24BML-TR is a DC-DC boost switching regulator optimized for constant-current white LED driver applications. It features an internal 750mA switch and operates at a fixed frequency of 1.2MHz. The device supports an input voltage range from 2.5V to 10V and includes a 24V overvoltage protection (OVP) threshold. It utilizes pulse width modulation (PWM) for dimming control and is housed in an 8-pin VFDFN package with an exposed pad.

LED Driver IC Feature Summary

• Integrates a high-efficiency boost converter topology with an internal power switch for compact design.
• Provides precise constant-current regulation suitable for driving white LEDs.
• Incorporates analog and PWM dimming capabilities for brightness control.
• Features built-in overvoltage protection to safeguard connected loads.

LED Driver IC Applications

• White LED backlighting for portable electronic devices
• Constant-current LED lighting drivers
• Battery-powered illumination systems

LED Driver IC Procurement Notes

Verify the specific suffix '24BML' confirms the 24V OVP rating and 8-MLF package variant. Ensure compatibility with Microchip's lead-free specifications. Confirm the tape-and-reel packaging format matches production requirements. Cross-reference the datasheet revision date to ensure current electrical characteristics are applied.

LED Driver IC Selection Notes

Select this component when a compact, high-frequency boost solution is required for single-string white LED applications. The 1.2MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Verify that the input supply voltage remains within the 2.5V to 10V range during operation.
