Key Features
- Wide 3 V to 60 V input range covers automotive, industrial, and telecom supply rails in a single design
- 3 MHz switching frequency enables use of tiny external inductors and capacitors, minimizing PCB area
- Ultra-low 3.5 µA quiescent current extends battery life in always-on or light-load IoT applications
- Current-mode PWM control with synchronous switching delivers high efficiency across the full 1 A load range
Applications
The LT8619EMSE#PBF targets automotive and industrial power supplies that must regulate from high input voltages down to low output rails with minimal heat dissipation. Its ultra-low quiescent current makes it ideal for battery-operated IoT sensors and remote monitoring nodes where standby power must be minimized. High 3 MHz switching supports compact, low-profile converter designs for space-constrained enclosures.

Frequently Asked Questions
What is the maximum input voltage the LT8619EMSE#PBF can handle, and which supply rails does that cover?
The LT8619EMSE#PBF accepts input voltages from 3 V up to 60 V, covering 12 V automotive battery rails, 24 V industrial supplies, and 48 V telecom bus voltages. This wide range eliminates the need for pre-regulation in most systems, reducing total component count.
How does the 3 MHz switching frequency benefit board space in a compact automotive ECU design?
Operating at 3 MHz allows the use of inductors as small as 1 µH and ceramic output capacitors in the 1 µF to 10 µF range, significantly shrinking the converter footprint compared to 300 kHz designs that require 10x larger magnetics for equivalent ripple performance.
What quiescent current does the LT8619EMSE#PBF draw in light-load mode, and why does it matter for battery-powered IoT?
The device draws only 3.5 µA quiescent current at no load, extending battery runtime in always-on sensor nodes and IoT edge devices that spend most of their time in sleep state. A 1000 mAh coin cell can power the standby rail for over 300 hours on quiescent current alone.
Which package does the LT8619EMSE#PBF use, and how does it compare footprint-wise to larger regulator packages?
The LT8619EMSE#PBF is housed in the MSE (MSOP-8) 8-pin small-outline package with a 3 mm x 3 mm body and 0.65 mm pitch, occupying far less PCB area than a standard 8-pin SOIC package which is roughly 6 mm x 5 mm, enabling denser power distribution networks.
