DC DC Switching Controllers datasheet and documents for LTC3899MPFE#PBF

LTC3899MPFE#PBF

DC DC Switching Controllers Overview

The LTC3899MPFE#PBF is a low quiescent current, triple output synchronous switching regulator controller from Analog Devices. It integrates two buck and one buck-boost controller channels to drive all N-channel power MOSFET stages. The device operates with an input voltage range of 4.5V to 60V and supports output voltages from 800mV to 60V. It features a switchable frequency between 105kHz and 835kHz, with a typical no-load quiescent current of 39uA. Packaged in a 38-TSSOP-EP, it includes control features such as soft start, tracking, and enable.

DC DC Switching Controllers Feature Summary

Integrates dual buck and single buck-boost controllers for multi-rail power distribution
Supports high input voltages up to 60V with low standby current consumption
Provides independent TRACK/SS pins for synchronized startup sequencing

DC DC Switching Controllers Applications

Automotive always-on systems requiring multiple regulated rails
Distributed DC power systems in industrial equipment
Battery-operated digital devices needing extended run time

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when sourcing. Confirm the MP prefix denotes military grade temperature ratings suitable for harsh environments. Ensure compatibility with external MOSFET gate drive requirements before finalizing procurement specifications.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring three distinct output rails from a single controller IC. It is suitable for applications demanding precise voltage tracking and soft-start synchronization across multiple outputs. Consider thermal management capabilities inherent to the exposed pad package for high-current implementations.

DC DC Switching Controllers Part Context

This part belongs to the LTC3899 family of low IQ synchronous controllers. It shares architectural similarities with other members like the LTC3899IFE but differs in packaging and potentially temperature grading. The MP variant specifically targets ruggedized applications compared to standard commercial grade equivalents.
