The LT8619IMSE#PBF is a high-efficiency, high-speed synchronous monolithic step-down switching regulator from LT, capable of delivering 1.2A of continuous current. It operates over a wide input voltage range of 3V to 60V and consumes only 6µA of quiescent current in Burst Mode operation, making it suitable for battery-powered applications.
Key features include a fast minimum switch-on time of 30ns, low output ripple of 10mVP-P at no load, and a synchronizable fixed frequency operation from 300kHz to 2.2MHz. The regulator achieves up to 92% efficiency and has a low dropout voltage of 360mV at 0.5A. An accurate 1V enable pin threshold allows for programmable undervoltage lockout or shutdown, reducing input supply current to below 0.6μA.
The LT8619IMSE#PBF includes internal compensation and peak current mode topology, enabling fast transient response and good loop stability with small inductors. It features a Power Good flag that signals when the output voltage is within ±7.5% of the programmed value. This component is AEC-Q100 qualified for automotive applications.
Available in a thermally enhanced 10-lead 3mm x 3mm DFN package with an exposed pad for low thermal resistance, this regulator is designed for surface mount applications. Its compact size and robust performance make it ideal for automotive systems, industrial supplies, and other power management applications requiring high efficiency and low quiescent current.
The input voltage range is 3V to 60V.
The maximum continuous output current is 1.2A.
It consumes 6µA of quiescent current when regulating 12VIN to 3.3VOUT in Burst Mode operation.
The typical output ripple at no load is 10mVP-P.
The operating temperature range is -40°C to 125°C.
It is supplied in a 10-lead DFN exposed pad package.
