IMX101U-TL

Overview

The IMX101U-TL is a single-output LED driver IC from the InnoSwitch3-MX series by Power Integrations. It integrates a DC-DC controller with an internal switch for flyback topology applications. The device supports analog and PWM dimming capabilities. It operates within a supply voltage range of 4.75 V to 5.25 V. The output voltage range is specified as 3 V to 22 V. The component is housed in a 28-HSOP package with thermal pad.

Feature Summary

• Integrates a DC-DC controller with an internal power switch for compact design
• Supports both analog and PWM dimming methods for flexible control
• Utilizes flyback topology for efficient power conversion

Applications

• LED backlighting systems
• General LED lighting drivers
• Flyback converter designs

Procurement Notes

Verify the specific ordering suffix and package variant against official datasheets to ensure compatibility with thermal requirements. Confirm moisture sensitivity level handling procedures during assembly. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Ensure the selected reel or cut tape quantity matches production needs without relying on general inventory estimates.

Selection Notes

Choose this component for applications requiring integrated switching and control in a small form factor. The internal switch simplifies bill of materials compared to discrete solutions. Consider the 28-HSOP package for surface mount assembly constraints. Verify that the required output voltage falls within the 3 V to 22 V operational range. Evaluate thermal management strategies suitable for the HSOP footprint.

Part Context

The IMX101U-TL belongs to the InnoSwitch3-MX family, which focuses on high-efficiency power supplies for monitors and TVs. This series emphasizes single-stage power conversion with multiple independent outputs in other variants, while this specific model provides a single regulated output. It represents Power Integrations' approach to integrating power switches with advanced control logic.

Replacement Considerations
