MAX8595XETA+TG05

LED Driver IC Overview

The MAX8595XETA+TG05 is a high-efficiency, step-up DC-DC converter designed for LED lighting applications. It operates with an input voltage range of 2.6 V to 5.5 V and provides a regulated output voltage up to 36 V. The device delivers a constant current of 25 mA through a single channel, utilizing a boost topology at a switching frequency of 1 MHz. It supports PWM dimming for white LEDs and includes thermal derating options. The component is housed in an 8-pin TDFN package and functions within a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• High-efficiency step-up conversion architecture optimized for driving multiple white LEDs from low-voltage sources.
• Integrated constant current regulation with pulse-width modulation (PWM) dimming capability for precise brightness control.
• Built-in thermal derating mechanism to maintain performance and reliability under elevated temperature conditions.

LED Driver IC Applications

• Portable white LED lighting systems
• Battery-powered illumination devices
• Backlighting for displays requiring high efficiency

LED Driver IC Procurement Notes

Verify the specific suffix TG05 against official Analog Devices documentation to confirm pinout and electrical characteristics, as suffixes often denote tape-and-reel packaging or specific manufacturing lot codes rather than functional changes. Confirm availability status directly with authorized distributors, as this part number may be subject to limited supply or obsolescence notices. Ensure the procurement source provides valid RoHS compliance data matching the ZETA designation.

LED Driver IC Selection Notes

Select this component when designing circuits that require efficient step-up conversion from a single-cell lithium-ion battery or similar low-voltage source to drive series-connected white LEDs. The 25 mA output current and 36 V maximum output voltage make it suitable for applications requiring moderate LED strings. Consider the TDFN-8 package size for space-constrained designs and verify that the 1 MHz switching frequency aligns with electromagnetic interference constraints in the target system.
