CAT4134HV2-GT2

Overview

The CAT4134HV2-GT2 is a two-channel boost LED driver IC from onsemi, designed for high-voltage applications. It operates within an input voltage range of 2.8 V to 4.2 V and supports output currents up to 250 mA at the high level and 5 mA at the low level. The device utilizes a TDFN-12 package and functions across a temperature range of -40°C to +85°C. This component is currently listed as obsolete by the manufacturer.

Feature Summary

• Dual-channel boost topology for independent LED string control
• Integrated current regulation with specified high and low output levels
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• LED lighting driver circuits
• Automotive interior illumination systems
• General-purpose high-voltage LED arrays

Procurement Notes

Verify end-of-life status before design finalization. Confirm RoHS compliance documentation availability. Check for alternative sourcing channels due to discontinuation. Ensure supply chain stability for production runs. Validate pinout compatibility if substituting with similar legacy parts.

Selection Notes

Evaluate thermal performance within the specified operating temperature range. Consider the TDFN-12 package constraints for PCB layout. Assess input voltage stability against the 2.8 V to 4.2 V operational window. Review channel isolation requirements for dual-string configurations. Verify current settings match target LED forward voltage characteristics.
