Texas Instruments High-Performance Analog Voltage Regulators - Linear + Switching LP873245RHDRQ1

The LP873245-Q1 is a dual high-current buck converter and dual linear regulator designed for automotive applications, featuring AEC-Q100 qualification for reliability in harsh environments. It operates within an input voltage range of 2.8 V to 5.5 V and provides two step-down DC/DC converters with programmable output voltages from 0.7 V to 3.36 V, capable of delivering up to 2 A per phase. The device also includes two linear regulators with output voltages ranging from 0.8 V to 3.3 V and a maximum output current of 300 mA. This product supports advanced features such as automatic phase adding and shedding, remote differential feedback voltage sensing, and programmable output-voltage slew rates. It operates at a switching frequency of 2 MHz and includes spread-spectrum mode for reduced electromagnetic interference (EMI). Additional protections include output short-circuit and overload protection, overtemperature warning, overvoltage protection, and undervoltage lockout. The LP873245-Q1 is packaged in a 28-pin VQFN format with wettable flanks, making it suitable for surface mount applications. It is ideal for use in automotive head units, camera modules, and radar system ECUs, providing a robust solution for power management in demanding environments.
