LT1947EMS#TRPBF

Special Purpose Regulators Overview

The LT1947EMS#TRPBF is a highly integrated multiple output DC/DC converter designed for TFT-LCD panels. It contains two independent switching regulators and provides three outputs. The device operates with an input voltage range of 2.7V to 8V and features a switching frequency of 3MHz. It is housed in a 10-MSOP package and supports an operating temperature range from -40°C to +85°C.

Special Purpose Regulators Feature Summary

• Highly integrated multiple output DC/DC converter architecture
• Contains two independent switching regulators for flexible power distribution
• Optimized specifically for TFT-LCD panel applications

Special Purpose Regulators Applications

• TFT-LCD panel power supply systems
• Portable display devices requiring compact power solutions
• Embedded systems utilizing LCD interfaces

Special Purpose Regulators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the manufacturer part number matches Analog Devices Inc. specifications exactly. Ensure compatibility with the required 10-MSOP footprint during PCB design review. Check current availability status as lead times may vary by region.

Special Purpose Regulators Selection Notes

Select this component when designing power stages for TFT-LCD displays requiring multiple regulated rails from a single IC. The 3MHz switching frequency allows for smaller passive components compared to lower frequency alternatives. Ensure the input voltage source remains within the 2.7V to 8V operational window for stable regulation across all outputs.

Special Purpose Regulators Part Context

This part belongs to the LT1947 family of specialized power management ICs. It is distinct from general-purpose buck or boost converters due to its multi-output configuration tailored for display drivers. The EMS#TRPBF designation specifies the MSOP package and reel packaging format for automated assembly processes.

Special Purpose Regulators Replacement Considerations

Direct substitutes must match the 3-output, 2-switcher topology and 10-MSOP package. Verify equivalent input voltage ranges and switching frequencies. Cross-reference thermal performance and pinout compatibility before integration into existing designs.
