LP87524-Q1 - 10A Quad-Output Automotive Buck | TI
MPN： LP87524-Q1 ✓ 啟用中LP87524-Q1 概覽
A buck converter is a DC-DC step-down regulator that reduces a higher input voltage to a lower output voltage. As a power management IC (PMIC), the LP87524-Q1 integrates multiple switching rails into a single device, reducing board space and system cost compared to discrete regulators.
Key features include 2MHz switching frequency, integrated power switches, load-current measurement without external sense resistors, and programmable start-up/shutdown delays and sequences. These sequences can synchronize with enable signals and GPIOs to control external regulators, load switches, and processor resets. The device's high integration eliminates external current-sense resistors, simplifying layout.
The LP87524-Q1 is designed to power automotive application processors like TDA4, AM62A, and AM26x series. Its four outputs can supply core, memory, I/O, and peripheral rails with high efficiency. The programmable sequencing enables safe power-up and power-down of complex SoCs, preventing latch-up or data corruption.
Typical applications include ADAS, infotainment, cluster displays, telematics, and in-vehicle networking. The 10A capability supports high-performance CPUs and GPUs. The wide input voltage range allows direct connection to automotive 12V/24V buses.
When designing with LP87524-Q1, ensure adequate input capacitance and thermal vias for the exposed pad. The programmable sequence feature must be configured correctly via I2C to match the processor's power sequencing requirements.

典型應用
LP87524-Q1 適用於 6 應用s: Automotive ADAS Processor Power, Automotive Infotainment System, Automotive Instrument Cluster, Automotive Telematics/Gateway, Automotive Camera Sensor Power, Industrial Robotics (Automotive-Grade).
Automotive ADAS Processor Power
The LP87524-Q1 delivers 10A across 4 rails to power ADAS SoCs like TDA4VL21HGAALZRQ1. Its 2MHz switching and integrated switches minimize solution size, while programmable start-up sequences ensure safe power sequencing for the processor. The load-current measurement feature allows monitoring without external sense resistors. This makes it ideal for camera processing and object recognition systems in vehicles.
推薦
Automotive Infotainment System
The LP87524-Q1 provides multiple stable rails for infotainment SoCs like AM62A1-Q1. With 4 outputs and 10A total, it can supply core, memory, and I/O voltages. The 2MHz switching frequency reduces inductor size, enabling compact PCB layout. Programmable delays allow coordinated power-up of display and audio subsystems, preventing pop noise and startup glitches.
推薦
Automotive Instrument Cluster
For instrument clusters, the LP87524-Q1 offers four regulated outputs to power the cluster controller, display driver, and sensors. Its 10A capability ensures stable operation under dynamic loads. The AEC-Q100 qualification and wide temperature range enable reliable operation in harsh vehicle environments, while the integrated load-current measurement assists in diagnostics without extra components.
推薦
Automotive Telematics/Gateway
The LP87524-Q1 is suitable for telematics control units and gateways, providing separate rails for the application processor, modem, and CAN transceivers. The 2MHz switching frequency allows small filter inductors, and programmable start-up sequences handle the modem's power ramp requirements. With integrated switches, it replaces multiple single-output regulators, simplifying the BOM.
推薦
Automotive Camera Sensor Power
LP87524-Q1 can power multiple camera sensors and their processing chips. Its four outputs provide separate bias rails (e.g., 3.3V, 1.8V, 1.2V) with 10A total, enough for sensor arrays. The low noise and high PSRR at 2MHz help maintain image quality. Programmable sequencing ensures sensors power up before the image processor, avoiding initialization errors.
推薦
Industrial Robotics (Automotive-Grade)
The LP87524-Q1's automotive qualification also suits industrial robotics in demanding environments. It provides 10A across four outputs for motor control MCUs, sensors, and communication interfaces. The 2MHz switching reduces EMI and allows compact power stages. The integrated load-current measurement helps monitor subsystem health, and programmable sequences enable controlled shutdown during fault conditions.

- Automotive AEC-Q100 qualification (對比Consumer PMICs)
設計說明
The LP87524-Q1 integrates four buck converters with a 2MHz switching frequency. Use 10uF input capacitors close to each VIN pin and 22uF output capacitors for each rail. Ensure low ESR capacitors are selected to minimize ripple and voltage transients.
The VQFN-26-HR-EP package has an exposed pad that must be soldered to a large copper pour. With 10A total output, power dissipation can reach 2-3W. Use thermal vias under the pad and connect to a ground plane to maintain junction temperature below 125°C.
Do not omit the programmable start-up delays; incorrect sequencing may cause processor latch-up. The load-current measurement function requires no external sense resistor, but the I2C registers must be configured correctly. Refer to the TI application note for recommended register settings.
