MP7230GLE-Z

Overview

The MP7230GLE-Z is a synchronous Buck-Boost or Buck LED driver IC designed for automotive infrared applications. It operates within a 6 V to 42 V input voltage range and delivers up to 1.2 A in Buck-Boost mode or 3 A in Buck mode. The device features a fixed switching frequency of 410 kHz and supports PWM dimming. Qualified under AEC-Q100 standards, it functions reliably between -40°C and +150°C junction temperature. Packaged in a 19-pin QFN (3x4 mm) with wettable flanks, it integrates internal switches for compact design.

Feature Summary

• Supports both Buck and Buck-Boost topologies for flexible LED current regulation
• AEC-Q100 qualified for automotive reliability and durability
• Includes overcurrent protection with latch-off mode for enhanced safety
• Features configurable thermal derating via remote NTC temperature sensing

Applications

• Driver monitoring systems
• Automotive infrared LED lighting
• Turn indicator lights

Procurement Notes

Verify the specific suffix against official Monolithic Power Systems documentation to confirm package type and qualification status. Ensure the selected variant matches the required operating temperature range and packaging format for your assembly process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and supply chain integrity before finalizing procurement orders.

Selection Notes

Select this component when designing automotive infrared LED circuits requiring high efficiency across varying input voltages. The fixed 410 kHz frequency aids in EMI management compared to higher-frequency alternatives. Consider the 19-QFN package constraints for thermal dissipation and PCB layout. Verify that the 1.2 A or 3 A output capabilities align with the target LED load requirements and system power budget.

Part Context

This device belongs to the MP7230 series of single-channel LED drivers from Monolithic Power Systems. It shares functional similarities with the MPQ7230GLE-AEC1-Z but may differ in specific qualification or packaging details. The series targets automotive lighting applications, offering integrated power switches to reduce external component count and simplify board space utilization for modern vehicle electronics.
