Overview
The LT8604EDDBM#TRPBF is a high-efficiency, synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.2 V to 42 V and delivers up to 120 mA of output current. The device features an adjustable switching frequency from 200 kHz to 2.2 MHz and maintains a typical quiescent current of 1.7 uA. It provides one positive adjustable output starting at 0.78 V. The component is housed in a 12-pin LQFN package (12-WFDFN Exposed Pad) and supports operation temperatures from -40°C to +125°C.
Feature Summary
- Synchronous buck topology for high efficiency across the load range
- Wide 42V input voltage capability suitable for industrial applications
- Adjustable switching frequency allows optimization for size or noise
- Low quiescent current enhances battery life in standby modes
Applications
- Industrial control systems requiring isolated or non-isolated power rails
- Battery-powered equipment needing efficient step-down conversion
- Embedded systems with microcontrollers or sensors
- Telecommunications infrastructure power distribution
Procurement Notes
Verify the exact suffix TRPBF indicates tape and reel packaging when ordering. Confirm the EDDBM variant corresponds to the 12-pin LQFN package rather than other available footprints. Ensure compatibility with the required thermal pad soldering process for the exposed pad design. Check RoHS compliance status against specific regional regulations if applicable.
Selection Notes
Select this part when input voltages exceed standard 36V regulators but remain below 42V. Choose based on the 120mA current limit if loads are light; higher current variants like the LT8608 may be needed for heavier loads. Consider the 12-pin footprint availability in the target PCB layout. Verify that the minimum output voltage of 0.78V meets the lowest system rail requirement.
Part Context
This component belongs to the LT8604 family of synchronous buck converters. It shares architectural similarities with the LT8608 but differs in current capacity and pinout. The LT8604 series is designed for compact designs where space and efficiency are critical. It complements other Analog Devices PMICs offering similar voltage ranges but different form factors.
Replacement Considerations
LT8604CAV#TRPBF offers similar electrical performance but uses a different LQFN-12 package configuration. LT8604EDDBM#TRMPBF is the same device but in cut-tape packaging instead of reel. Direct functional substitutes require matching the 42V input rating and 120mA output capability.
