LTC3833EFE#PBF

DC DC Switching Controllers Overview

The LTC3833EFE#PBF is a synchronous step-down DC/DC controller from Analog Devices, designed for high-performance power management applications. It operates with an input voltage range of 4.5 V to 38 V and supports output voltages from 600 mV to 5.5 V. The device delivers up to 25 A of output current and features a programmable switching frequency adjustable between 200 kHz and 2 MHz. Key electrical specifications include a maximum load regulation of -1%, a typical quiescent current of 15 µA, and a supply current of 2 mA. It functions within a temperature range of -40°C to +125°C and is housed in a 20-lead TSSOP package with an exposed pad.

DC DC Switching Controllers Feature Summary

• Integrated synchronous buck topology eliminates the need for external Schottky diodes, improving efficiency and reducing component count.
• Supports differential remote output sensing to maintain precise voltage regulation at the load point despite PCB trace resistance.
• Features a wide switching frequency range allowing optimization for either transient response or electromagnetic interference (EMI) performance.

DC DC Switching Controllers Applications

• Point-of-load (POL) conversion for industrial equipment
• Power distribution systems in telecommunications infrastructure
• Voltage regulation for embedded computing and data storage subsystems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF confirms lead-free and RoHS compliance status before procurement. Confirm the TSSOP-EP-20 package variant matches your PCB footprint requirements. Ensure the selected distributor provides valid traceability documentation for this Analog Devices part number. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

DC DC Switching Controllers Selection Notes

Select this controller when a single-phase, high-current buck solution is required with minimal external components. It is suitable for designs needing fast transient response and high efficiency across a wide input voltage range. Consider the thermal performance of the TSSOP-EP package for your specific power dissipation needs. Evaluate the 2 MHz maximum frequency against EMI constraints for your application environment.

DC DC Switching Controllers Part Context

This component belongs to the LTC3833 family of synchronous step-down controllers. It shares functional similarities with other Analog Devices PMICs but is distinct in its specific 25 A current capability and 38 V maximum input rating. The device is often evaluated using dedicated demonstration boards such as the DC1516A series provided by the manufacturer.
