Overview
The LT1534IS-1#PBF is an ultralow noise, high-efficiency switching regulator manufactured by Analog Devices Inc. It utilizes a boost topology to provide a single adjustable output with a maximum current of 2 A. The device operates from an input voltage range of 2.7 V to 23 V and features a programmable switching frequency between 20 kHz and 250 kHz. It includes a shutdown function and maintains a typical operating supply current of 12 mA. The component is housed in a 16-pin SOIC package and supports an industrial temperature range from -40°C to +125°C.
Feature Summary
- Ultralow noise performance suitable for sensitive analog circuits
- High efficiency boost converter topology
- Programmable switching frequency for optimization
- Integrated shutdown control
Applications
- Portable instrumentation requiring low noise power
- Battery-powered systems needing efficient voltage step-up
- Sensor signal conditioning power supplies
- Communication equipment power management
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the IS-1 variant matches the required electrical specifications against the official Analog Devices datasheet. Ensure the SOIC-16 package footprint aligns with the PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when ultralow noise is critical for downstream circuitry. The boost topology is appropriate for stepping up lower battery voltages to higher system rails. Consider the 2 A output capability and the wide input voltage range when designing for varying source conditions. Verify thermal requirements for the SOIC-16 package under maximum load conditions.
Part Context
This part belongs to the LT1534 series of switching regulators designed for applications demanding superior noise performance compared to standard switchers. It serves as a specialized power management solution within the Analog Devices portfolio, targeting designs where linear regulators are inefficient or standard switchers introduce unacceptable ripple.
Replacement Considerations
Consult the official Analog Devices documentation for verified cross-reference part numbers. Do not assume functional equivalence with other boost controllers without validating pinout and electrical parameters.
