LT8570IMS8E#PBF

The LT8570IMS8E#PBF is a low noise, high efficiency, integrated switching voltage regulator produced by Linear Technology, designed to deliver a continuous 1.5 A output current. This product is categorized as a DC/DC Buck Regulator, a type of switching regulator commonly used in portable communications, consumer applications and other systems requiring a small form factor and/or low noise operation.

The LT8570IMS8E#PBF provides superior performance with several features, such as a wide 4.5V to 36V input voltage range, adjustable switching frequency up to 1.2 MHz, and a low quiescent current of 8.2 mA.

The LT8570IMS8E#PBF can also be programmed to offer a variety of features and capabilities, including: internal power control loop, feedback compensation, current limit, soft-start/reset, operating temperature, and frequency synchronization. A temperature range down to -40°C and up to +85°C makes the LT8570IMS8E#PBF a great choice for applications operating in extreme temperatures.

The LT8570IMS8E#PBF is built with the Buck Buck topology, which uses two power transistors to switch the output voltage of a linear regulator to a required value. In this topology, the regulator receives an input voltage and then switches two output power transistors, one ON and one OFF. The output voltage is also controlled by feedback, where the voltage control loop compares the output voltage to a reference voltage and adjusts the duty cycle of the power transistors.

The LT8570IMS8E#PBF also makes use of several innovative features to reduce the output noise produced by the regulator, such as spread spectrum frequency modulation, a wide pulse-width modulation switching frequency range, and a slew rate controlled output transistor.

Other features of the product include a built-in deglitch circuit to reduce output transients and an overvoltage protection circuit to prevent overvoltage conditions. The product also includes an undervoltage lockout, thermal shutdown protection, and a programmable power good output.

The LT8570IMS8E#PBF is an ideal solution for a variety of applications requiring a power management component, such as portable communication devices, automotive electronics, network equipment, low voltage processors, and battery-powered devices. This product also offers excellent feedback, excellent efficiency, and a low input-to-output voltage differential.
