What are the key features of LT8619EMSE-5#PBF?
- Wide input voltage range from 3 V to 60 V covering automotive, industrial, and telecom power rails in a single synchronous buck topology
- Ultra-low quiescent current of 3.5 µA enabling always-on battery-powered applications with minimal standby power consumption
- 3 MHz switching frequency allowing the use of small external inductors and capacitors for compact, high-efficiency PCB layouts
What is LT8619EMSE-5#PBF used for?
The LT8619EMSE-5#PBF is well-suited for automotive power systems, industrial field instruments, and telecom equipment where input voltages can range from low 3 V logic rails up to 60 V battery or bus voltages. Its 3.5 µA quiescent current makes it an excellent choice for always-on IoT sensors, remote monitoring nodes, and battery-backed systems where minimizing standby power drain is critical. Engineers also use it in solar and energy harvesting power stages where wide input voltage swings must be efficiently regulated to a fixed 5 V output.

Frequently Asked Questions
How does the LT8619EMSE-5#PBF achieve ultra-low standby power in battery-powered IoT applications?
The LT8619EMSE-5#PBF draws only 3.5 µA of quiescent current during light-load operation, which translates to extremely long battery life in always-on IoT sensors and remote monitoring devices. At this current level, a small 1000 mAh battery could theoretically power the regulator's quiescent consumption for years, making it an ideal choice for wireless sensor nodes and energy-harvesting systems.
What input voltage range does the LT8619EMSE-5#PBF support, and which industrial applications benefit from this wide range?
The LT8619EMSE-5#PBF accepts input voltages from 3 V to 60 V, with a nominal operating point at 12 V. This wide range accommodates automotive 12 V and 24 V batteries, 48 V telecom bus rails, and industrial 36 V to 60 V supply lines, making it a versatile solution for field instruments, factory automation controllers, and ruggedized embedded systems.
Why is a 3 MHz switching frequency significant in the LT8619EMSE-5#PBF's PCB design?
Operating at 3 MHz allows the LT8619EMSE-5#PBF to use significantly smaller inductors and output capacitors compared to lower-frequency regulators, reducing the overall PCB footprint and bill of materials cost. For a 1 A output current, this high switching frequency enables inductors in the low-µH range, which are smaller, lighter, and less expensive than the 10 µH to 47 µH components required at 300 kHz designs.
