- Wide 7.5 V to 36 V input range covering 12 V automotive and 24 V industrial bus voltages in a single device
- 1.2 A output current capability at 5 V fixed output for powering MCUs, sensors, and communication ICs
- Constant-frequency current-mode control ensuring predictable EMI signature and fast transient response
- Automotive-grade MSOP-8 exposed-pad package enabling efficient thermal dissipation in under-hood and harsh environment applications
What is LT3663IMS8E-5#TRPBF used for?
The LT3663IMS8E-5#TRPBF is designed for automotive electronics operating from 12 V or 24 V vehicle bus rails, stepping down to 5 V for microcontrollers, CAN transceivers, and sensors in body control modules and ADAS systems. Industrial panel controllers and transportation equipment powered from 24 V to 36 V supplies also use it to derive regulated 5 V logic rails. Its 36 V maximum input tolerance accommodates load-dump transients and 24 V truck electrical systems without external protection components.

Frequently Asked Questions
What input voltage range does LT3663IMS8E-5#TRPBF support for automotive and industrial applications?
The LT3663IMS8E-5#TRPBF accepts input voltages from 7.5 V to 36 V, covering standard 12 V automotive batteries, 24 V truck electrical systems, and 24 V industrial bus rails. The 36 V maximum input also handles common automotive load-dump transients, reducing the need for external transient voltage suppressors in most designs.
How much output current can LT3663IMS8E-5#TRPBF deliver at its 5 V output?
The device delivers up to 1.2 A continuous output current at the fixed 5 V output rail. This is sufficient to simultaneously power a 32-bit MCU (typically 100–200 mA), several CAN or LIN transceivers (50 mA each), and multiple sensors (10–50 mA each) in a typical automotive body control module or industrial I/O node.
How does constant-frequency current-mode control benefit EMI management in the LT3663IMS8E-5#TRPBF?
Constant-frequency switching generates harmonics at predictable, fixed intervals, making EMI filtering straightforward with standard LC input and output filters designed for that specific frequency. Current-mode control adds inherent cycle-by-cycle current limiting and faster transient response compared to voltage-mode control, both critical for meeting automotive CISPR 25 radiated emissions requirements in vehicle electronic modules.
What package does LT3663IMS8E-5#TRPBF use and how does the exposed pad improve thermal performance?
The device uses an MSOP-8 package with an exposed thermal pad (EP) on the bottom, which conducts heat directly to the PCB copper plane. The exposed pad significantly reduces junction-to-ambient thermal resistance compared to standard MSOP-8 without EP, allowing the regulator to sustain 1.2 A output without exceeding junction temperature limits across the automotive -40°C to +125°C temperature range.
