Overview
The LT8619IMSE-5#PBF is a synchronous monolithic buck regulator manufactured by Analog Devices. It operates with an input voltage range of 3 V to 60 V and delivers a continuous output current of 1.2 A. The device features a fixed 5 V output and utilizes a variable switching frequency ranging from 300 kHz to 2.2 MHz. Quiescent current is specified at 6 uA. It is housed in a 16-lead MSOP package and supports operation temperatures from -40°C to +125°C.
Feature Summary
- Integrates high-side and low-side N-channel power switches for efficient synchronous rectification
- Supports adjustable switching frequencies between 300 kHz and 2.2 MHz to optimize external component size
- Features ultra-low quiescent current consumption to extend battery life in standby modes
Applications
- Industrial point-of-load regulation
- Automotive electronics systems
- Telecommunications infrastructure power supplies
Procurement Notes
Verify the specific suffix #PBF confirms lead-free and RoHS compliance status. Confirm the IMSE designation matches the required MSOP-16 thermal performance and pinout for your PCB layout. Ensure the -5 suffix corresponds to the fixed 5 V output requirement rather than other available voltage options within the series.
Selection Notes
Select this component when a wide input voltage range up to 60 V is required alongside moderate output current capabilities. The variable frequency feature allows designers to trade off efficiency against electromagnetic interference levels. Verify that the 1.2 A output capability meets the peak load demands of the target application circuit.
Part Context
This part belongs to the LT8619 family of high-speed synchronous buck regulators. It shares architectural similarities with other members like the LT8619EMSE-5#PBF but differs in temperature grade and package variant. The family is designed for applications requiring high efficiency across broad input voltage ranges.
Replacement Considerations
LT8619EMSE-5#PBF serves as a direct functional substitute within the same product family, offering identical electrical specifications with potential differences in operating temperature range or package thermal characteristics.
