LTC3900IS8#PBF

Overview

The LTC3900IS8#PBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7V to 60V and supports output currents up to 15A. The device features a fixed switching frequency of 400kHz, adjustable via an external resistor. It includes programmable soft-start, cycle-by-cycle current limit, and overvoltage protection. The component is housed in an 8-lead MSOP package and is rated for operation between -40°C and +85°C.

Feature Summary

Synchronous buck controller architecture for high efficiency
Integrated power MOSFET drivers
Programmable frequency and soft-start capabilities

Applications

Point-of-load regulation in industrial systems
Battery-powered equipment power management
Telecommunications infrastructure power supplies

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the IS8 designation matches the required MSOP-8 thermal performance. Cross-reference the manufacturer's latest datasheet revision to ensure pinout compatibility with existing designs. Validate that the operating temperature range meets the environmental requirements of the target application.

Selection Notes

Select this controller for applications requiring a compact solution with integrated drivers. Ensure the external inductor selection aligns with the 400kHz fixed frequency to maintain stability. Verify that the input voltage range covers the maximum source voltage including transients. Check that the load current does not exceed the internal switch ratings under worst-case thermal conditions.

Part Context

This component belongs to the LTC3900 family of synchronous step-down controllers. It shares functional similarities with other members like the LTC3900CS8 but differs in package type and thermal characteristics. The family is designed for efficient power conversion in space-constrained environments.

Replacement Considerations

The LTC3900CS8 is a documented alternative within the same product family. Verify package compatibility as the CS8 uses a different footprint than the IS8.
