Texas Instruments LP8774x-Q1 | Demoboard LP877451Q1EVM

Description

The LP8774x-Q1 device is designed to meet the power management requirements of the AWR and IWR MMICs in various automotive and industrial radar applications. The device has three step-down DC/DC converters, a 5 V boost converter and a 1.8 V/3.3 V LDO. The LDO is powered from the boost and intended for xWR and peripheral devices IO supply. The device is controlled by an SPI serial interface and by enable signal.The step-down DC/DC converters support programmable switching frequency of 17.6 MHz, 8.8 MHz or 4.4 MHz and have low noise across wide frequency range which enables LDO-free power solution with minimal or no additional passive filtering. LP8774x-Q1 device offers flexible external component selection to optimize the solution in terms of performance or cost. The features of the device target safety-relevant applications with system-safety requirements up to ASIL-C level.
