MIC2292C-15YML

LED Driver IC Overview

The MIC2292C-15YML is a high-frequency PWM boost regulator optimized for constant-current white LED driver applications. It operates at a fixed switching frequency of 1.6MHz and supports an input voltage range from 2.5V to 10V. The device features an internal Schottky diode and provides 15V output overvoltage protection with less than 1% line and load regulation. It delivers a switch current rating of 750mA and utilizes a compact 8-pin MLF package.

LED Driver IC Feature Summary

• Integrates an internal Schottky diode to minimize external component count
• Provides stable operation with ceramic capacitors
• Offers two levels of output overvoltage protection options
• Supports analog and PWM dimming control

LED Driver IC Applications

• Constant-current white LED lighting drivers
• Backlighting systems for portable devices
• RF-sensitive applications requiring specific frequency bands

LED Driver IC Procurement Notes

Verify the manufacturer origin, as Micrel was acquired by Microchip Technology. Confirm the suffix 'YML' corresponds to the 8-MLF (2x2) package and lead-free status. Ensure the part number includes the 'C' designation for the 15V OVP variant. Check RoHS compliance documentation for regulatory requirements.

LED Driver IC Selection Notes

Select this component when a compact solution for white LEDs is required without sensitive RF interference concerns due to the 1.6MHz frequency. It is suitable for battery-powered designs operating between 2.5V and 10V. Choose this variant specifically for its 15V overvoltage protection threshold compared to other models in the series.

LED Driver IC Part Context

This device belongs to the MIC2292/93C family of high-frequency PWM white LED drivers. It shares architectural similarities with the MIC2293C but differs in switching frequency and overvoltage protection settings. The product line emphasizes small size and efficiency by requiring only four external components.

LED Driver IC Replacement Considerations

MIC2292-15YML-TR is a parameter-equivalent alternative within the same product family.
