STOD02PUR

Special Purpose Regulators Overview

The STOD02PUR is a dual DC-DC converter integrated circuit designed specifically for powering AMOLED displays. It operates with an input voltage range of 2.5V to 4.5V and provides two synchronous step-down outputs. The positive output delivers up to 4.6V, while the negative output ranges from -2.3V to -5.9V. The device supports a maximum output current of 0.15A and functions within an operating temperature range of -40°C to 85°C. It is housed in a compact 12-pin DFN EP package.

Special Purpose Regulators Feature Summary

• Dual synchronous step-down architecture optimized for AMOLED display power requirements
• Integrated negative voltage generation capability alongside positive rail regulation
• Compact surface-mount packaging suitable for space-constrained mobile designs

Special Purpose Regulators Applications

• Powering AMOLED display panels in smartphones
• Portable electronic devices requiring efficient display backlighting
• Mobile communication equipment with OLED interfaces

Special Purpose Regulators Procurement Notes

Verify the specific suffix PUR indicates tape and reel packaging when ordering. Confirm the 12-DFN EP package dimensions match your PCB footprint design. Ensure input voltage sources remain within the 2.5V to 4.5V operational limits to maintain regulator stability. Check thermal dissipation requirements for the exposed pad in high-density layouts.

Special Purpose Regulators Selection Notes

Select this component when designing systems requiring dedicated dual-rail power for AMOLED displays. It is suitable for applications needing both positive and negative supply rails from a single low-voltage source. Consider its 0.15A current limit when sizing power budgets for smaller display modules. Evaluate the 12-DFN package for assembly compatibility with existing surface mount lines.
