MIC2289-34BML-TR

LED Driver IC Overview

The MIC2289-34BML-TR is a DC-DC boost regulator designed for LED driving applications. It accepts an input voltage range of 2.5V to 10V and provides a fixed output voltage of 34V, selected from options including 15V, 24V, and 34V. The device operates at a switching frequency of 1.2MHz and features an internal Schottky diode. It supports switch currents exceeding 500mA, with specific variants capable of delivering up to 750mA.

LED Driver IC Feature Summary

• Integrated internal Schottky diode for simplified circuit design
• Fixed output overvoltage protection (OVP) options available in 15V, 24V, and 34V configurations
• Supports both analog dimming and PWM control interfaces for brightness adjustment

LED Driver IC Applications

• White LED driver circuits
• Portable electronic devices requiring high-brightness LED illumination
• Battery-powered systems needing efficient step-up regulation

LED Driver IC Procurement Notes

Verify the suffix 'BML' corresponds to the 8-pin VFDFN package with exposed pad and tape-and-reel packaging. Confirm the '34' designation matches the required 34V output specification. Ensure compatibility with Microchip Technology's current manufacturing standards and datasheet revisions before procurement.

LED Driver IC Selection Notes

Select this component when a fixed 34V output is required from a low-voltage source between 2.5V and 10V. Choose based on the need for integrated OVP and internal rectification. Consider the 1.2MHz frequency for compact passive component sizing. Verify that the 500mA to 750mA current capability meets the LED load requirements.
