What are the key features of LT8614EUDC#TRPBF?
- 42V input, 4A synchronous step-down Silent Switcher with 2.5 µA quiescent current for ultra-low standby power in battery applications
- Current-mode PWM control with Silent Switcher EMI reduction architecture meeting CISPR 25 Class 5 automotive radiated emissions limits
- Wide 3.4V to 42V input range covering 12V automotive, 24V industrial, and 36V telecom bus standards in a single compact design
What is LT8614EUDC#TRPBF used for?
The LT8614EUDC#TRPBF is engineered for always-on automotive subsystems such as body control modules and telematics units where the 2.5 µA quiescent current minimizes battery drain during vehicle-off standby periods. Its 42V input tolerance handles load dump transients on 12V and 24V vehicle power rails without additional clamping, while the Silent Switcher architecture reduces conducted and radiated EMI for sensitive AM/FM receiver coexistence. The device also suits industrial IoT nodes powered from 24V field bus rails and solar-energy-harvesting systems requiring efficient conversion across varying input voltages from 3.4V to 42V.

Frequently Asked Questions
How does the 2.5 µA quiescent current of LT8614EUDC#TRPBF extend battery life in an always-on IoT sensor node?
At 2.5 µA quiescent current, the LT8614EUDC#TRPBF draws only 60 µWh per day from a 3.7V Li-ion cell in sleep mode, compared to 2.4 mWh for a regulator with 1 mA quiescent current. For a sensor node sleeping 23 hours per day, this difference extends a 2000 mAh battery life from approximately 3 months to over 2 years without changing the battery capacity.
What input voltage range does LT8614EUDC#TRPBF cover, and which automotive bus standards does it directly handle?
The LT8614EUDC#TRPBF accepts 3.4V to 42V input, covering the standard 12V automotive battery rail with load dump transients up to 40V, as well as 24V heavy-vehicle electrical systems and 36V mild-hybrid bus architectures. This single device eliminates the need for separate TVS clamping diodes in many automotive ECU designs, reducing BOM count by 2 to 4 components.
How does the Silent Switcher architecture of LT8614EUDC#TRPBF reduce EMI compared to conventional buck regulators?
Silent Switcher technology places bypass capacitors and switch nodes in a dual-die arrangement that cancels differential AC current loops, reducing peak radiated emissions by 10 dB to 20 dB compared to conventional buck converters at 400 kHz to 2 MHz switching frequencies. This pre-certified EMI performance helps automotive designs comply with CISPR 25 Class 5 limits for AM radio band protection without requiring large external EMI filters.
For a 24V to 5V, 3A point-of-load conversion in an industrial PLC, what efficiency does LT8614EUDC#TRPBF typically achieve at full load?
Operating from a 24V input to a 5V output at 3A load, the LT8614EUDC#TRPBF achieves approximately 90% to 92% conversion efficiency with a suitable inductor in the 1 µH to 3.3 µH range at 400 kHz switching frequency. The 4A peak current rating provides 25% headroom above the 3A load, maintaining regulation during brief 3.5A current spikes without triggering overcurrent protection in PLC digital output drivers.
