PMIC – Voltage Regulators – DC DC Switching Regulators

The LT8570EMS8E#PBF is a monolithic filter, voltage regulator, and switch mode power supply all in one. It is designed to provide a regulated output voltage that is isolated from primary source. The on-chip, low-noise, high-voltage bootstrap switch and an adjustable charge pump make the LT8570EMS8E#PBF ideal for modern high-frequency boards without an active voltage amplifier. Additionally, its ability to support up to 4 outputs makes it ideal for applications requiring multiple output voltages.

The LT8570EMS8E#PBF utilizes a buck-boost topology to achieve the maximum efficiency and power transfer. By switching rapidly between buck and boost modes, the device can continually maintain an output voltage above, below, or equal to the input voltage. This technique optimizes efficiency and allows for very small voltage drop-out even when used with extremely low input voltages such as those found on modern mobile devices. Furthermore, the device’s high frequency operation allows for very small form factors.

The LT8570EMS8E#PBF uses a fixed frequency current-mode control to ensure stable operation over a wide range of load and line conditions. Additionally, the device features a full protection suite including over-current, over-temperature, over-voltage and under-voltage protections. This provides a reliable, robust solution with minimal additional components.

The LT8570EMS8E#PBF has many applications, ranging from automotive to industrial use. In automotive applications, the device may be used to power electrical control units (ECUs), entertainment systems, and other devices that require a regulated voltage output. In industrial applications, the device may be used to power fan speed controllers, brushless DC (BLDC) motor controllers, and other precision electronic devices. Additionally, the device can be used in laptop or tablet charging ports and power banks to provide a regulated output for charging.

The LT8570EMS8E#PBF is a powerful monolithic filter, voltage regulator, and switch mode power supply all in one. Its buck-boost topology allows for efficient transfer of power and allows for operation from very low input voltages. In addition, its over-current, over-temperature, over-voltage, and under-voltage protections provide a robust, reliable solution with minimal additional components. The device can be used in many applications, including automotive, industrial and portable electronics.
