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 step-down 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 current-sense 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 output-voltage overshoot and in-rush current.

레퍼런스 디자인

PMP30819 — PMIC 및 LDO을 사용하는 3개 출력의 오토모티브 전력 공급 레퍼런스 설계

이 다중 출력 공급 장치는 멀티 채널 IC(PMIC) LP87653-Q1을 통해 5V 입력 전압에서 맞춤형 ASIC에 전원을 공급합니다. 이 PMIC에 4개의 레일이 있지만, 3상은 사용되지 않으며 고객의 요구에 따라 LDO(저손실 레귤레이터)를 통해 1.1VA(여기서 A는 민감한 부하의 아날로그와 동일)가 생성됩니다. 2.5VA 및 1.1VA에 사용되는 LDO는 TPS745-Q1입니다. 두 LDO 모두 3.3V에서 전원이 공급되어 LDO 1.1VA의 손실을 낮추고 2개의 전력 저항이 입력에 추가됩니다.
