MAX8596ZETA-T

LED Driver IC Overview

The MAX8596ZETA-T is a high-efficiency, single-channel LED lighting driver IC from the MAX8596 series. It functions as a boost DC-DC converter with an internal switch, designed for driving white LEDs. The device operates within an input voltage range of 2.6 V to 5.5 V and delivers a regulated output current of 25 mA per channel. It supports PWM dimming and constant current regulation. The maximum output voltage reaches 36 V, while the switching frequency is fixed at 1 MHz. It is housed in an 8-lead TDFN package (3x3 mm) with an exposed pad and operates across a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Integrates a high-efficiency boost converter topology with an internal power switch for compact LED drive solutions.
• Provides precise constant current regulation suitable for driving multiple white LEDs in series configurations.
• Supports analog and PWM dimming methods for flexible brightness control applications.

LED Driver IC Applications

• White LED backlighting for portable devices
• General LED lighting driver circuits
• Display illumination systems

LED Driver IC Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'T' indicates tape-and-reel packaging. Check for RoHS compliance status and ensure the part matches the exact MAX8596ZETA-T designation to avoid confusion with similar variants like the MAX8596XETA-T. Request official datasheets and lot traceability documentation upon order confirmation.

LED Driver IC Selection Notes

Select this component when a single-channel, high-efficiency boost driver is required for white LED arrays. Ensure the application input voltage falls between 2.6 V and 5.5 V. Verify that the required LED forward voltage does not exceed the 36 V output limit. Consider the 25 mA output current capability and 1 MHz switching frequency for thermal and EMI management. The TDFN-8 package is suitable for space-constrained surface-mount designs.

LED Driver IC Part Context

This part belongs to the MAX8595/MAX8596 family of high-efficiency step-up converters optimized for LED lighting. These devices are designed to replace linear regulators in battery-powered applications to extend runtime. The MAX8596 variant specifically targets applications requiring higher output voltages compared to the MAX8595, supporting up to eight white LEDs in series depending on the configuration.

LED Driver IC Replacement Considerations

The MAX8596XETA-T is a related variant within the same family. Verify if the X-series specifications meet the specific design requirements before substitution. Cross-reference pinouts and electrical characteristics with official Analog Devices documentation to ensure compatibility.
