LTC3807IFE#PBF

DC DC Switching Controllers Overview

The LTC3807IFE#PBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc., housed in a 20-lead TSSOP package with an exposed thermal pad. It operates within an input voltage range of 4V to 38V and supports adjustable output voltages from 0.8V to 24V. The device features a programmable switching frequency between 50kHz and 900kHz, with a typical no-load quiescent current of 50µA. It includes integrated soft-start, tracking capabilities, and power-good indicators, designed for high-efficiency power management in demanding environments.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with required input voltage ranges and thermal dissipation requirements for the target application environment. Cross-reference datasheet revisions for any recent manufacturing changes.

DC DC Switching Controllers Selection Notes

Select this component when a wide input voltage range up to 38V is required alongside low standby current consumption. Consider the 20-TSSOP-EP package for thermal performance in space-constrained designs. Evaluate the need for external current sensing versus internal DCR sensing based on system accuracy requirements.

DC DC Switching Controllers Part Context

This part belongs to the LTC3807 family of high-performance buck controllers. It is distinct from integrated regulators as it requires external power stages. The IFE suffix denotes the industrial temperature range and TSSOP-EP packaging variant, differentiating it from other package options like QFN.

DC DC Switching Controllers Replacement Considerations

Consult official substitution guides for pin-compatible alternatives such as the LTC3816 or LT3763. Verify that replacement parts support the same 4V to 38V input range and 24V maximum output capability.
