Overview
The LT1534CS#TRPBF is an ultralow noise 2A switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7 V to 23 V and delivers a single adjustable output from 1.3 V to the input voltage. The device features an operating supply current of 12 mA and integrates a 2 A switch. It is available in a 16-lead SSOP package and supports boost, Cuk, and flyback topologies.
Feature Summary
- Designed to significantly reduce conducted and radiated electromagnetic interference (EMI) through proprietary circuit architecture.
- Integrates a high-current 2 A power switch for efficient step-up and inverted converter applications.
- Provides ultralow output noise performance suitable for sensitive analog and RF circuits.
Applications
- Portable instrumentation requiring low-noise power supplies
- RF communication systems needing clean DC power
- Battery-powered devices utilizing boost or flyback topologies
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the component is sourced from authorized distributors to ensure authenticity. Check for RoHS compliance documentation as required by your manufacturing standards. Ensure the SSOP-16 footprint matches your PCB design constraints before finalizing procurement.
Selection Notes
Select this component when EMI reduction and low output noise are critical system requirements. It is appropriate for designs requiring up to 2 A output current from a 2.7 V to 23 V input range. Consider the SSOP-16 package size if board space allows. Evaluate thermal management needs based on the expected load current and input-output differential.
Part Context
The LT1534 series represents a class of switching regulators focused on minimizing electromagnetic interference. This part belongs to the broader portfolio of power management ICs from Analog Devices, specifically targeting applications where signal integrity is paramount. It complements other regulators that may prioritize efficiency over noise performance.
Replacement Considerations
The LT1534CS-1#PBF is a related variant within the same family. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part meets the same EMI and noise requirements for your specific application.
