MAX1985ETP+

LED Driver IC Overview

The MAX1985ETP+ is a DC-DC boost regulator designed for LED driver applications, manufactured by Analog Devices Inc. (Maxim Integrated). It features an internal switch and provides six outputs with a switching frequency of 1 MHz. The device supports PWM dimming control and operates within a supply voltage range of 2.7 V to 5.5 V. It is housed in a 20-pin TQFN package with an exposed pad, suitable for surface mount installation. The component functions as a step-up converter optimized for backlight regulation.

LED Driver IC Feature Summary

• Integrates a high-efficiency internal switch for compact power conversion
• Supports pulse-width modulation (PWM) dimming for precise brightness control
• Provides multiple regulated outputs from a single boost topology

LED Driver IC Applications

• LCD backlight regulation
• Portable electronic display systems
• Multi-zone LED lighting circuits

LED Driver IC Procurement Notes

Verify the specific suffix designation when ordering, as variations such as MAX1985ETP+T may indicate different packaging formats like tape and reel versus tube. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

LED Driver IC Selection Notes

Select this component for designs requiring a multi-output boost solution with integrated switching capabilities. The 1 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 20-TQFN package dimensions for PCB layout constraints and thermal dissipation requirements in space-sensitive portable devices.
