MP1518DJ-LF-Z

LED Driver IC Overview

The MP1518DJ-LF-Z is a step-up converter designed for driving up to six series white LEDs from a single-cell lithium-ion battery. It operates within an input voltage range of 2.6 V to 6 V and delivers a switch current of 350 mA. The device features a fixed switching frequency exceeding 1 MHz, housed in a TSOT-23-6 package. Key electrical parameters include a low feedback voltage of 104 mV and an operating temperature range from -40°C to +85°C.

LED Driver IC Feature Summary

• Integrates a power MOSFET capable of driving up to six series-connected white LEDs
• Utilizes a constant-frequency architecture with current control mode for precise LED regulation
• Incorporates open-load shutdown functionality via OV pin monitoring to prevent overvoltage conditions

LED Driver IC Applications

• Backlighting for LCD panels in virtual reality (VR) applications
• Driving WLED arrays powered by single-cell lithium-ion batteries
• General LED lighting driver circuits requiring compact surface-mount solutions

LED Driver IC Procurement Notes

Verify the specific suffix 'LF-Z' against the manufacturer's official documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure compatibility with the required TSOT-23-6 footprint and validate that the 350 mA output current meets the target LED array requirements before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when designing systems requiring a boost topology for single-cell battery operation. It is suitable for applications needing integrated power switching and high efficiency up to 87%. Consider the TSOT-23-6 package size constraints and the 1 MHz switching frequency for EMI management compared to lower-frequency alternatives.
