Overview
The LT3502AIMS#PBF is a step-down switching regulator manufactured by Analog Devices Inc. It operates at selectable frequencies of 750kHz or 2.2MHz and provides a maximum output current of 400mA. The device accepts an input voltage range from 3.6V to 40V. It features two integrated low-dropout (LDO) regulators with fault protection capabilities. The component is housed in a 16-lead MSOP package with an exposed thermal pad, designed for surface-mount applications.
Feature Summary
- Integrates dual fault-protected LDOs alongside the primary switching regulator
- Supports selectable switching frequencies of 750kHz and 2.2MHz
- Provides high input voltage tolerance up to 40V
Applications
- Battery-powered portable equipment requiring efficient voltage conversion
- Industrial systems utilizing wide input voltage ranges
- Embedded control circuits needing multiple regulated supply rails
Procurement Notes
Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the AIM variant meets the required industrial temperature specifications. Ensure the MSOP-16 footprint matches the target PCB design constraints. Validate that the supplier source is authorized to prevent counterfeit components.
Selection Notes
Select this component when a compact solution is needed for converting higher voltages to lower levels. The dual LDO feature reduces external component count compared to separate regulator designs. Consider the thermal performance requirements due to the exposed pad package. Evaluate the efficiency benefits of the 2.2MHz option for smaller passive components.
Part Context
This part belongs to the LT3502 family of monolithic switching regulators. It is distinct from synchronous converters as it utilizes a P-channel switch. The device integrates the controller, switch, and protection circuitry into a single small footprint, simplifying the design process for space-constrained power management applications.
Replacement Considerations
LT3502AIMS#TRPBF serves as the tape-and-reel equivalent of this tube-packaged component. Verify pin compatibility if substituting with other Linear Technology step-down regulators.
