3 Description
The LP876242-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, generating
four 1-phase outputs. The device settings can be
changed by I2C-compatible serial interface or by a
SPI serial interface.
The switching clock is forced to PWM mode and
the phases are interleaved. The switching can
be synchronized to an external clock and spreadspectrum
mode can be enabled to minimize the
disturbances.
The LP876242-Q1 device includes protection and
diagnostic mechanisms such as register and interface
CRC, short-circuit protection, thermal monitoring, and
shutdown. The LP876242-Q1 device can notify the
processor of these events through the interrupt
handler, allowing the processor to take action in
response.
