Overview
The LT8604IDDBM#TRPBF is a high-efficiency synchronous step-down switching regulator from Analog Devices. It operates with an input voltage range of 3.2 V to 42 V and delivers up to 120 mA output current. The device features a fixed switching frequency range of 200 kHz to 2.2 MHz and ultralow quiescent current of 1.7 µA. It provides adjustable output voltage starting from 0.78 V. The component is housed in a 10-WFDFN exposed pad package and supports operation temperatures from -40°C to +125°C.
Feature Summary
- High efficiency synchronous buck topology exceeding 90% at light loads
- Ultralow quiescent current for extended battery life
- Integrated silent switcher technology for reduced EMI
Applications
- Battery-powered portable instrumentation
- Industrial control systems
- Automotive electronics
Procurement Notes
Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the IDDBM package variant matches the required footprint. Ensure the manufacturer is Analog Devices Inc. Check RoHS compliance status before integration.
Selection Notes
Select this part for applications requiring low standby current and wide input voltage ranges. The 120 mA limit suits light-load scenarios. Compare against LT8604CAV for package differences. Ensure thermal management fits the DFN form factor.
Part Context
This component belongs to the LT8604 family of synchronous buck regulators. It shares core architecture with variants like LT8604IDDBM#TRMPBF but differs in packaging quantity. The series targets compact power designs requiring high efficiency.
Replacement Considerations
LT8604IDDBM#TRMPBF serves as a cut-tape alternative. LT8604CAV#TRPBF offers a different LQFN-12 package. Verify pin compatibility and thermal performance before substitution.
