Overview
The IS32LT3961-ZLA3-TR is a constant-current LED driver IC featuring a single output channel with a 2 A capability. It utilizes a buck regulator topology and supports both analog and PWM dimming methods. The device operates within an input voltage range of 5 V to 60 V, delivering a regulated output voltage of 6 V. Packaged in an eTSSOP-16 (5 mm x 6.4 mm) format, it includes integrated output fault reporting for system diagnostics. The component is rated for operation across an extended temperature range from -40°C to +150°C.
Feature Summary
- Integrates a step-down (buck) DC/DC converter topology for efficient LED power regulation.
- Provides precise constant current control with support for both analog and pulse-width modulation dimming.
- Includes built-in output fault reporting mechanisms to enhance system reliability and diagnostic capabilities.
Applications
- Automotive exterior lighting systems
- High-power LED illumination modules
- Industrial lighting fixtures requiring wide input voltage tolerance
Procurement Notes
Verify the specific suffix ZLA3-TR against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Ensure that the application circuit design accommodates the 60 V maximum input rating and the thermal requirements associated with the eTSSOP-16 package at full load conditions.
Selection Notes
Select this component when a single-channel high-current solution with buck topology is required. It is suitable for designs needing wide input voltage flexibility up to 60 V. Consider the integrated fault reporting if system monitoring is critical. Verify compatibility with the desired dimming interface, as the device supports both analog and PWM control signals.
