MIC2293-15YML-TR

LED Driver IC Overview

The MIC2293-15YML-TR is a high-frequency PWM white LED driver IC manufactured by Microchip Technology. It operates as a boost DC-DC converter with an internal switch, supporting an input voltage range of 2.5 V to 10 V and delivering a maximum output current of 750 mA. The device features a fixed switching frequency of 2 MHz and includes 15 V overvoltage protection (OVP). It supports both analog and PWM dimming methods for brightness control. The component is housed in an 8-MLF® (2x2 mm) surface-mount package and is rated for operation within a junction temperature range of -40°C to 125°C.

LED Driver IC Feature Summary

• Integrates a 2 MHz high-frequency boost converter with an internal power switch for compact design.
• Provides 15 V overvoltage protection to safeguard connected LED loads from transient voltage spikes.
• Supports dual dimming modes, allowing for both analog and pulse-width modulation control.
• Operates efficiently across a wide input voltage range suitable for single-cell lithium battery applications.

LED Driver IC Applications

• Backlighting for mobile phones and handheld devices
• White LED illumination in portable consumer electronics
• General-purpose LED lighting drivers in compact form factors

LED Driver IC Procurement Notes

Verify the specific suffix '15' indicates the 15 V overvoltage protection variant when sourcing replacements. Confirm the 8-MLF package dimensions match the PCB footprint requirements. Ensure compatibility with the required dimming signal type, as the device supports both analog and PWM inputs. Check RoHS compliance status if operating in regulated environments.

LED Driver IC Selection Notes

Select this component when a compact solution for driving white LEDs from a single-cell lithium source is required. The 2 MHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Consider the 15 V OVP feature if the application environment poses risks of voltage transients exceeding standard LED ratings. Evaluate thermal performance given the small 2x2 mm package size under continuous load conditions.
