MAX1883EUP

Overview

The MAX1883EUP is a quad-output TFT LCD DC-DC converter housed in a 20-pin TSSOP package. It operates from a 2.7V to 5.5V supply with a 700µA supply current. The device integrates one high-power step-up converter and two low-power charge pumps to generate three independent output voltages. It supports operating temperatures from -40°C to +85°C.

Feature Summary

• Integrates one high-power step-up converter and dual regulated charge pumps for multi-rail generation
• Provides three independent output voltages from a single input source
• Utilizes current-mode PWM control with 500kHz or 1MHz switching frequencies

Applications

• TFT-LCD monitors
• Portable display systems requiring multiple voltage rails
• Battery-powered consumer electronics with LCD interfaces

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm the specific suffix matches the required thermal and packaging specifications. Review the latest datasheet for any updates regarding lead-free compliance and RoHS status before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring three distinct voltage levels from a single low-voltage source. Ensure the application demands a compact surface-mount solution compatible with the 20-TSSOP footprint. Validate that the input voltage range aligns with the system's power supply architecture.

Part Context
