Overview
The LT3667EMSE#TRPBF is a monolithic triple power supply from Analog Devices, integrating a 400mA buck switching regulator and two 200mA low dropout linear regulators (LDOs). It operates with an input voltage range of 4.3V to 40V. The switching frequency is adjustable between 243kHz and 2.2MHz. The device is housed in a 16-lead MSOP package with an exposed pad.
Feature Summary
- Integrates a high-efficiency step-down switching regulator with dual fault-protected LDOs for comprehensive power management.
- Provides three independent output rails from a single input source, simplifying board layout and component count.
- Features adjustable switching frequency to optimize efficiency and minimize external passive component size.
Applications
- Portable battery-powered equipment requiring multiple voltage rails
- Industrial control systems with mixed analog and digital power needs
- Automotive infotainment and sensor interfaces
Procurement Notes
Verify the suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the EMSE variant meets the required operating temperature range for your specific application environment. Ensure the 16-lead MSOP EP footprint matches your PCB design guidelines before finalizing procurement.
Selection Notes
Select this component when a compact solution is needed to generate three distinct voltages from a single input source. The integrated fault protection on the LDO outputs adds robustness compared to discrete solutions. Consider the 400mA buck current limit against total load requirements to ensure adequate headroom.
Part Context
This part belongs to the LT3667 family of triple power supplies. It combines switching and linear regulation technologies to address diverse load requirements within a small form factor. The EMSE designation specifies the commercial temperature grade and MSOP package type.
Replacement Considerations
Check for LT3667IMSE#TRPBF if industrial temperature range is required. Verify pinout compatibility with existing designs before substituting. Review datasheet differences regarding thermal performance and electrical specifications between variants.
