MAX8595ZETA-T

LED Driver IC Overview

The MAX8595ZETA-T is a high-efficiency, single-output step-up (boost) converter LED driver IC manufactured by Analog Devices Inc./Maxim Integrated. It operates from an input voltage range of 2.6 V to 5.5 V and provides a regulated output current of 25 mA for driving white LEDs. The device supports PWM dimming control and features a fixed switching frequency of 1 MHz. It is housed in an 8-pin TDFN package with dimensions of 3x3 mm and is rated for operation between -40°C and +85°C.

LED Driver IC Feature Summary

• Integrates a high-efficiency boost converter topology optimized for white LED illumination applications.
• Supports precise analog and PWM dimming control for brightness adjustment.
• Maintains constant current regulation to ensure stable LED performance.

LED Driver IC Applications

• White LED lighting systems
• Portable electronic device backlighting
• Battery-powered indicator circuits

LED Driver IC Procurement Notes

Verify the exact suffix against official manufacturer documentation, as variations such as ZETA+T may indicate lead-free compliance or specific tape-and-reel configurations. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the ordering part number matches the required packaging format and environmental specifications before finalizing procurement.

LED Driver IC Selection Notes

Select this component when designing compact LED drivers requiring a wide input voltage range and high efficiency. The 1 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Ensure the application requires a single-channel constant current source within the specified 25 mA limit and operates within the defined temperature range.

LED Driver IC Part Context

This part belongs to the MAX8595 series of high-efficiency step-up converters designed specifically for LED applications. It is part of Maxim Integrated's portfolio of power management solutions, now under Analog Devices Inc., focusing on portable electronics and battery-operated devices where space and efficiency are critical constraints.

LED Driver IC Replacement Considerations

Check for direct pin-compatible substitutes within the same family, such as other MAX8595 variants with different suffixes for packaging or temperature grades. Verify that any alternative maintains the 25 mA output current capability and 1 MHz switching frequency to preserve board layout and performance characteristics.
