STOD03ATPUR

Special Purpose Regulators Overview

The STOD03ATPUR is a dual DC-DC converter integrated circuit designed for AMOLED display power management. It features two independent output channels with fixed and adjustable voltage settings. The device operates from a minimum input voltage of 2.3 V. One channel provides a fixed 4.6 V output, while the second offers an adjustable range from -5.4 V to -2.4 V. Both outputs support up to 150 mA load current. The IC utilizes a 1.5 MHz switching frequency and is housed in a compact 12-DFN package.

Special Purpose Regulators Feature Summary

• Dual-channel architecture providing separate regulation paths for display biasing requirements
• Integrated high-frequency switching topology enabling the use of small external passive components
• Designed specifically for driving active matrix organic light-emitting diode panels

Special Purpose Regulators Applications

• Power supply for AMOLED display modules
• Bias voltage generation for OLED pixel arrays
• Portable electronic devices requiring efficient display backlighting or emission control

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized distribution channels due to market availability fluctuations. Confirm package integrity upon receipt as surface-mount devices are sensitive to handling. Ensure storage conditions meet manufacturer specifications to prevent moisture damage prior to reflow soldering processes.

Special Purpose Regulators Selection Notes

Select this component when designing circuits for AMOLED displays requiring specific negative and positive rail voltages. Evaluate thermal performance within the operating temperature range of -40°C to +85°C. Consider the 12-DFN footprint constraints during PCB layout to ensure adequate heat dissipation and signal integrity for the switching nodes.

Special Purpose Regulators Part Context

This part belongs to the STOD03B series of power management ICs. It serves as a specialized solution for display drivers, distinct from general-purpose regulators. The series focuses on integrating multiple conversion stages into a single compact form factor to reduce board space and simplify system design for visual output applications.

Special Purpose Regulators Replacement Considerations

Check datasheets for pin-compatible alternatives within the same family. Verify that substitute parts match the exact output voltage tolerances and current capabilities required by the target display panel.
