LT8714IFE#PBF

DC DC Switching Controllers Overview

The LT8714IFE#PBF is a synchronous PWM DC/DC controller designed for four-quadrant output converters. It supports input voltages from 10V to 14V and generates bipolar outputs ranging from -5V to 5V with a switching frequency of 200kHz. The device provides an output current capability of ±5A, allowing the output voltage to cleanly transition through zero volts while sourcing and sinking current. It operates within a junction temperature range of -40°C to 125°C and utilizes a 20-TSSOP-EP package.

DC DC Switching Controllers Feature Summary

• Designed for four-quadrant operation enabling seamless transitions through zero volts
• Capable of both sourcing and sinking output current for bidirectional power flow
• Integrated synchronous PWM control architecture for high-efficiency conversion

DC DC Switching Controllers Applications

• Four-quadrant DC/DC converter designs requiring bipolar output
• Systems needing clean voltage transitions through zero volts
• Applications requiring simultaneous sourcing and sinking of output current

DC DC Switching Controllers Procurement Notes

Verify the complete part number including the suffix #PBF to ensure lead-free compliance and specific packaging configuration. Confirm that the 20-TSSOP-EP package footprint matches your PCB design requirements. Ensure thermal management strategies account for the specified junction temperature limits during operation. Cross-reference official Analog Devices documentation for any recent product change notices or material declarations relevant to this component.

DC DC Switching Controllers Selection Notes

Select this controller when a single IC must handle both positive and negative output regulation with bidirectional current capabilities. It is suitable for applications where the load may return energy to the source or require precise zero-volt crossing. Consider the 200kHz switching frequency for balancing efficiency and component size. Ensure the input voltage range aligns with the system's supply rails before implementation.

DC DC Switching Controllers Part Context

The LT8714 belongs to Analog Devices' family of synchronous PWM controllers specialized for complex power conversion topologies. Unlike standard unipolar regulators, this component addresses the specific needs of four-quadrant operation. It integrates the necessary drive signals for external synchronous MOSFETs, simplifying the design of advanced DC/DC converters compared to discrete solutions.
