Overview
The LT3480HMSE#PBF is a micropower synchronous buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6 V to 36 V and delivers up to 2 A of output current. The device features a fixed 2.4 MHz switching frequency and supports adjustable output voltages from 790 mV to 20 V. Key electrical parameters include a quiescent current of 70 uA during operation and 30 uA in shutdown mode. It utilizes a 10-lead MSOP package with an exposed pad for thermal management.
Feature Summary
- Integrates high-efficiency synchronous rectification with a low on-resistance internal switch
- Features Burst Mode operation to maintain high efficiency at light loads while minimizing output ripple
- Includes a boost Schottky diode and complete control logic within the monolithic die
Applications
- Battery-powered portable equipment requiring extended runtime
- Industrial systems with wide input voltage ranges
- Automotive electronics operating under varying supply conditions
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence. Confirm the HMSE designation corresponds to the MSOP-10 package variant. Ensure compatibility with required thermal dissipation standards for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when a fixed 2.4 MHz frequency is preferred over the adjustable range found in other LT3480 variants. It is suitable for designs prioritizing compact footprint via the MSOP package. Consider thermal performance requirements due to the exposed pad design for heat sinking.
Part Context
This part belongs to the LT3480 family of micropower synchronous step-down regulators. It shares core topology with variants like LT3480IMSE but differs in package type and temperature rating specifications defined by the manufacturer's coding system.
Replacement Considerations
LT3480IMSE#PBF offers similar electrical characteristics but may differ in package dimensions or temperature grade. Verify pinout compatibility and thermal resistance values before substituting.
