MIC3289-24YD6-TR Description

MIC3289-24YD6-TR Description

The MIC3289-24YD6-TR from Microchip Technology is a high-efficiency, 1.2MHz step-up DC-DC regulator designed for driving LEDs in backlighting applications. Packaged in a compact TSOT-23-6 form factor and supplied in Tape & Reel (TR), this ROHS3 Compliant and REACH Unaffected device integrates an internal 1.2A switch, enabling simplified PCB design and reduced external component count. With a wide input voltage range of 2.5V to 6.5V, it is optimized for battery-powered and low-voltage systems, delivering stable performance in space-constrained designs.

MIC3289-24YD6-TR Features

  • Integrated 1.2A Switch: Eliminates the need for an external MOSFET, reducing BOM cost and board space.
  • High Switching Frequency (1.2MHz): Enables the use of smaller inductors and capacitors, optimizing footprint.
  • Wide Input Range (2.5V–6.5V): Supports operation from single-cell Li-ion, Li-poly, or multi-cell alkaline/NiMH batteries.
  • Single Output Channel: Delivers precise current control for consistent LED brightness.
  • Surface-Mount TSOT-23-6 Package: Ideal for compact, high-density layouts in portable electronics.
  • MSL 1 (Unlimited): Suitable for extended storage and flexible manufacturing workflows.
