LYT1602D

LED Driver IC Overview

The LYT1602D is an LED lighting driver IC from the LYTSwitch-1 series, designed for universal input applications. It features a Buck topology with a single constant current output capable of delivering up to 91 mA. The device operates within an input voltage range of 90 VAC to 308 VAC and supports a maximum supply voltage of 308 V. Operating at a frequency of 20 kHz, it integrates single-stage PFC capabilities. The component is housed in an SOIC-8 package and functions reliably across a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Integrates primary-side regulation for simplified design
• Includes built-in single-stage power factor correction
• Supports wide universal AC input voltage ranges
• Combines controller, high-voltage switch, and feedback loop

LED Driver IC Applications

• LED lighting drivers
• General illumination systems
• Universal input power supplies

LED Driver IC Procurement Notes

Verify availability status as the LYT1602D is listed as obsolete or end-of-life by major distributors. Confirm if the tape-and-reel variant (LYT1602D-TL) is available for production needs. Ensure compliance with RoHS directives and check for any specific environmental certifications required for your region before finalizing procurement plans.

LED Driver IC Selection Notes

Select this component for low-power LED applications requiring integrated PFC and primary-side regulation. The SOIC-8 package suits surface-mount designs. Consider the 91 mA output limit and 20 kHz switching frequency when designing thermal management and EMI filters. Verify that the Buck topology aligns with the target LED string configuration.

LED Driver IC Part Context

Part of the LYTSwitch-1 family, which combines controller, high-voltage switch, and feedback loop into a single package. This integration reduces external component count and simplifies design for isolated flyback, buck, and boost converters. The series targets cost-sensitive, high-volume consumer and commercial lighting applications.

LED Driver IC Replacement Considerations

Check for the LYT1602D-TL variant, which offers the same electrical specifications but in a tape-and-reel package instead of tubes. No other direct functional substitutes are confirmed in the provided data.
