LT3663EMS8E#PBF

Overview

The LT3663EMS8E#PBF is a current mode step-down switching regulator manufactured by Analog Devices Inc. It features a fixed output voltage of 3.3V and supports a maximum output current of 1.2A. The device operates with an input voltage range from 7.5V to 36V. It utilizes an 8-pin MSOP EP package. The internal switch handles a typical current of 2A, while the switching frequency is set at 1100kHz. The component functions within an operating temperature range of -40°C to 125°C.

Feature Summary

Current mode control architecture for precise regulation
Programmable output current limit to manage system power dissipation
Integrated high-side switch reducing external component count

Applications

3.3V step-down converter circuits
Automotive power supply systems
Industrial DC-DC conversion applications

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. or its predecessor Linear Technology. Ensure the part status is active before procurement planning. Check RoHS directive compliance documentation for regulatory requirements in your region.

Selection Notes

Select this component when a fixed 3.3V output is required from a 7.5V to 36V input source. The 1.2A output current capability suits moderate load applications. The 8-pin MSOP EP package is suitable for space-constrained designs requiring thermal performance. Consider the 1100kHz frequency for balancing efficiency and passive component size.

Part Context

This part belongs to the LT3663 family of synchronous buck regulators. Variants exist with different fixed output voltages such as 1.2V and 5V. The EMS8E designation specifies the commercial/extended temperature grade and the MSOP EP package type. The #PBF suffix denotes environmental compliance.
