MAX8570EUT-T

Overview

The MAX8570EUT-T is a high-efficiency LCD boost converter with true shutdown, manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 2.7 V to 5.5 V and delivers up to 0.6 A output current. The device features an internal switching frequency of 800 kHz and is housed in a compact SOT-23-6 package. Designed for low-power applications, it supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates a high-efficiency boost converter topology optimized for LCD bias generation.
• Features true shutdown capability to minimize quiescent current consumption during inactive states.
• Utilizes an internal 800 kHz switching frequency to allow for the use of small external passive components.

Applications

• LCD bias voltage generation for portable displays
• Battery-powered handheld devices requiring efficient step-up conversion
• Low-power consumer electronics with strict power management requirements

Procurement Notes

Verify the specific manufacturer source, as listings may attribute this part to Rochester Electronics or Maxim Integrated. Confirm RoHS compliance status and check for obsolescence notices, as availability varies significantly across distributors. Ensure the ordering suffix matches the required tape-and-reel configuration for your assembly process.

Selection Notes

Select this component when designing circuits that require a compact, high-efficiency solution for boosting battery voltages to drive LCD panels. The SOT-23-6 package is suitable for space-constrained designs. Evaluate the 0.6 A current limit against your load requirements and ensure the input voltage range aligns with your battery chemistry.
