LTC4442EMS8E-1#TRPBF

Overview

The LTC4442EMS8E-1#TRPBF is a high-frequency gate driver designed to drive two N-channel MOSFETs in synchronous buck DC/DC converter topologies. It operates with a supply voltage range of 6 V to 9.5 V and delivers a peak output current of 5 A. The device features fast switching characteristics, including a rise time of 12 ns and a fall time of 8 ns, with a maximum propagation delay of 20 ns. It functions within an operating temperature range of -40°C to +85°C and is housed in an 8-pin MSOP package.

Feature Summary

Designed for driving N-channel MOSFETs in synchronous buck DC/DC converter applications
Provides high-speed switching capability with low propagation delay
Integrates independent high-side and low-side driver outputs

Applications

Synchronous buck DC/DC converters
High-frequency power management circuits
N-channel MOSFET gate drive stages

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the -1 variant designation matches the required half-bridge configuration. Ensure the MSOP-E-8 footprint aligns with the PCB layout. Cross-reference the manufacturer's latest datasheet for any updates on electrical specifications or recommended operating conditions prior to final procurement.

Selection Notes

Select this component for designs requiring dedicated high-speed drivers for synchronous rectification. The 5 A output current capability supports moderate-power MOSFETs. Consider the 6 V to 9.5 V supply range compatibility with standard logic levels. Evaluate thermal performance requirements given the small MSOP package size for the intended power dissipation levels.

Part Context

This part belongs to the Analog Devices LTC4442 series of high-frequency gate drivers. It is specifically engineered for synchronous buck converter applications, offering integrated high-side and low-side drive channels. The device simplifies design by providing robust gate drive signals necessary for efficient power conversion in compact form factors.
