Overview
The LT1616ES6#TRMPBF is a current mode PWM step-down DC/DC converter manufactured by Analog Devices Inc. It features an internal 0.6A power switch and is housed in a compact 6-lead SOT-23 package. The device supports a wide input voltage range starting from 3.6V and provides a positive adjustable output voltage beginning at 1.25V. It delivers up to 600mA of output current with a fixed switching frequency of 1.4MHz. The component operates within a temperature range of 0°C to +70°C.
Feature Summary
- Integrates a 0.6A power switch for efficient step-down conversion
- Supports wide input voltage range starting from 3.6V
- Provides adjustable output voltage down to 1.25V
- Utilizes current mode PWM control architecture
Applications
- Portable battery-powered equipment
- Industrial control systems
- Communication infrastructure power supplies
Procurement Notes
Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with surface-mount assembly processes. Confirm availability through authorized distributors as supply levels may vary. Cross-reference the Mouser part number 584-LT1616ES6#TRMPBF for accurate sourcing details.
Selection Notes
Select this component when a compact solution is required for low-to-medium current applications. The integrated 0.6A switch suits designs where external power transistors are undesirable. Verify that the 1.4MHz switching frequency aligns with EMI constraints and inductor size requirements. Ensure the input voltage exceeds the minimum 3.6V threshold for proper regulation.
Part Context
This part belongs to the LT1616 series of synchronous buck converters. It is designed for space-constrained applications requiring high efficiency in a small footprint. The SOT-23-6 package allows for easy integration into dense PCB layouts. It serves as a direct replacement for older generation regulators in similar form factors.
Replacement Considerations
Check for pin-compatible alternatives such as the LTC3410 or LTC3411 if higher current capability is needed. Verify thermal performance differences between packages. Ensure switching frequency compatibility to avoid redesigning passive components.
