3 Description
The LP8756x-Q1 device is designed to meet the
power-management requirements of the latest
processors and platforms in various automotive
power applications. The device contains four stepdown
DC/DC converter cores, which are configured
as a 4-phase output, 3-phase and 1-phase outputs,
2-phase and 2-phase outputs, one 2-phase and two
1-phase outputs, or four 1-phase outputs. The device
is controlled by an I2C-compatible serial interface and
by enable signals.
The automatic pulse-width-modulation (PWM) to
pulsed-frequency-modulation (PFM) operation (AUTO
mode), together with the automatic phase adding and
phase shedding, maximizes efficiency over a wide
output-current range. The LP8756x-Q1 supports
remote differential-voltage sensing for multiphase
outputs to compensate IR drop between the regulator
output and the point-of-load (POL) improving the
accuracy of the output voltage. The switching clock
can be forced to PWM mode and also synchronized
to an external clock to minimize the disturbances.
The LP8756x-Q1 device supports load-current
measurement without the addition of external currentsense
resistors. The device also supports
programmable start-up and shutdown delays and
sequences synchronized to enable signals. The
sequences can include GPIO signals to control
external regulators, load switches, and processor
reset. During start-up and voltage change, the device
controls the output slew rate to minimize outputvoltage
overshoot and in-rush current.
P87561IRNFRQ1属于集成电路(IC) > 稳压器 - DC-DC 开关稳压器。美国德州仪器公司制造生产的P87561IRNFRQ1稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC(电源管理集成电路)产品族中的产品是元器件级设备,用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件,设备提供的电力会通过该元件。
