Description
General part information
LP8769-Q1 Series
The LP8769x-Q1 device is designed to meet the power management requirements of the latest processors and platforms in various safety-relevant automotive and industrial applications. The device has four step-down DC/DC converter cores, that are configurable for five different phase configurations from one 4-phase output to four 1-phase outputs. The device settings can be changed by I2C-compatible serial interface or by a SPI serial interface.
The automatic PFM/PWM (AUTO mode) operation together with the automatic phase adding and phase shedding maximizes efficiency over a wide output-current range. The LP8769x-Q1 device supports remote differential voltage sensing for multiphase outputs to compensate IR drop between the regulator output and the point-of-load (POL) that improves the accuracy of the output voltage. The switching clock can be forced to PWM mode and the phases are interleaved. The switching can be synchronized to an external clock and spread-spectrum mode can be enabled to minimize the disturbances.
