LTC3807IUDC#TRPBF

DC DC Switching Controllers Overview

The LTC3807IUDC#TRPBF is a low quiescent current synchronous step-down switching regulator DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4V to 38V and supports output voltages from 800mV to 24V. The device features a programmable switching frequency between 50kHz and 900kHz, allowing for optimization of efficiency and external component size. It utilizes a 20-WFQFN (3x4) package with an exposed thermal pad for effective heat dissipation. The controller includes integrated soft-start, tracking, and current limit functions.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology with integrated low-side driver control
• Programmable switching frequency for design flexibility
• Built-in soft-start and output voltage tracking capabilities

DC DC Switching Controllers Applications

• Point-of-load regulation in industrial equipment
• Power distribution networks for embedded systems
• Battery-powered portable devices requiring high efficiency

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the I grade designation meets the required operating temperature range for your application environment. Ensure the 20-QFN footprint matches your PCB layout constraints before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this controller when a wide input voltage range up to 38V is required alongside low standby power consumption. The adjustable frequency feature allows designers to balance EMI performance against passive component size. Consider the exposed pad thermal requirements for high-current applications.

DC DC Switching Controllers Part Context

This component belongs to the LTC3807 family of synchronous step-down controllers designed for high-efficiency power management. It complements other Analog Devices PMIC solutions by offering flexible configuration options for various load requirements while maintaining compact form factors suitable for dense circuit board layouts.

DC DC Switching Controllers Replacement Considerations

LTC3807IFE#PBF offers identical electrical specifications but utilizes a 20-TSSOP-EP package instead of QFN. Designers must account for the physical footprint differences and thermal path variations when substituting packages within the same functional family.
