Key Features
- Wide 3V to 60V input range handles automotive and industrial supply voltages
- 3MHz switching frequency reduces external component size for ultra-compact designs
- 1A synchronous rectification achieves high efficiency without external catch diode
- Current-mode PWM control provides fast transient response and accurate current limiting
Applications
The LT8619EDD is designed for automotive and industrial power systems requiring regulation from high-voltage rails up to 60V down to low output voltages. Its 3MHz switching frequency and synchronous topology make it ideal for space-constrained PCBs in telematics units, industrial controllers, and 48V bus converters. The wide input range also suits systems powered from unregulated battery rails or legacy 24V/48V industrial supply buses.

Frequently Asked Questions
What is the maximum input voltage the LT8619EDD can safely handle?
The LT8619EDD accepts input voltages from 3V up to 60V, making it suitable for automotive 12V/24V/48V systems and industrial applications where supply rails may fluctuate well above standard logic levels.
How does the 3MHz switching frequency of the LT8619EDD benefit PCB layout?
Operating at up to 3MHz allows use of smaller inductors and capacitors compared to lower-frequency converters, enabling compact PCB designs. For a 12V-to-5V conversion at 1A, a 2.2µH inductor is typically sufficient, saving significant board area.
For which automotive or industrial applications is the LT8619EDD best suited?
The LT8619EDD is ideal for automotive telematics, ADAS modules, and 48V mild-hybrid systems needing a robust 1A regulated output. Its 60V input tolerance handles load-dump transients, and the synchronous rectifier delivers efficiency above 90% at typical 12V input conditions.
