The LP87725-Q1 device is designed to meet the power management requirements of the AWR, IWR and other MMICs in various automotive and industrial radar applications. The device has three step-down DC/DC converters, a LDO regulator and a load switch. The LDO is powered externally and intended for Ethernet device core supply. The load switch is intended to cut off the 3.3 V IO supply during the sensor sleep mode The device is controlled by an I2C 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 design with minimal or no additional passive filtering. LP87725-Q1 device offers flexible external component selection to optimize the design in terms of performance or cost. The features of the device target safety-relevant applications with system-safety requirements up to ASIL-B level.

This user's guide provides instructions to power-up and evaluate LP87725-Q1 device using the LP87725Q1EVM evaluation module (EVM) and software user interface (LP87725-Q1 GUI). By default LP87725Q1EVM has LP87725101RAGRQ1 device OTP version (17.6 MHz), but this EVM can also be used to evaluate another OTP device from LP8772x-Q1 product family.

CAUTION: Hot surface. Contact can cause burns. Do not touch!
