Description
General part information
LP87725-Q1 Series
The LP8772x-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 supplying Ethernet device or any other device in the system. The load switch is intended to cut off the 3.3 V IO supply during the sensor sleep mode. The device is controlled by I2C communication interface and by enable signals.
The low noise step-down DC/DC converters support factory programmed switching frequency of 17.6 MHz or 8.8 MHz or 4.4 MHz. High switching frequency and low noise across wide frequency range, enables LDO-free power solution which helps to reduce the solution cost and improve thermal performance. The switching clock is forced to PWM mode for excellent RF performance and can also be synchronized to an external clock. The LP8772x-Q1 device supports remote voltage sensing to compensate IR drop between the regulator output and the point-of-load (POL) which improves the accuracy of the output voltage.
The LP8772x-Q1 device supports programmable start-up and shutdown delays and sequences which are synchronized to the ENABLE signal. These sequences can also include GPO signal to control external regulators, load switches, and processor reset. The default settings for the device are programmed into nonvolatile memory (NVM) / one time programmable (OTP) memory at the factory and user cannot change the device default NVM / OTP settings. The device controls the output slew rate to minimize output voltage overshoot and in-rush current during device start-up.
