TPS65036x-Q1 - Automotive PMIC | Texas Instruments
MPN: TPS65036x-Q1 ✓ Hoạt độngTPS65036x-Q1 Tóm tắt
What is a PMIC? A Power Management IC integrates multiple power conversion and regulation functions, such as voltage regulators, LDOs, and battery management, into a single chip. PMICs are essential in automotive electronics to generate the various supply rails required by processors, sensors, and peripherals from a single battery input, reducing board space, cost, and complexity. The TPS65036x-Q1 sits in the power management hierarchy, specifically in the automotive camera/radar/MCU power sub-system.
Key features include a wide-input-voltage BUCK1 converter supporting up to 35V, allowing direct connection to automotive 12V/24V battery systems. Two additional low-voltage buck converters and a 300mA LDO provide multiple rails. The device supports forced fixed-frequency PWM mode or AutoPFM mode for efficiency across load ranges, optional spread-spectrum modulation for EMI reduction, and low-power operation controlled via pin or I2C.
The TPS65036x-Q1 is AEC-Q100 qualified for automotive reliability, with an operating temperature range up to +125°C. The integrated sequencing and I2C interface enable flexible power management and diagnostics. The 24-pin VQFN package with a 0.5mm pitch and 3.5x3.5mm footprint minimizes PCB area, critical in space-constrained camera modules.
Typical applications include automotive camera modules, radar units, and MCU power supplies in ADAS systems, where multiple regulated rails are needed from a single automotive battery. The device also supports infotainment and sensor fusion systems requiring low-noise, reliable power.
When designing with the TPS65036x-Q1, pay attention to thermal management: the buck converters and LDO can dissipate significant power at high input voltages and load currents. Ensure adequate copper pour and thermal vias to keep junction temperatures within limits. Also, properly configure the I2C address and default settings for your specific application variant.

Ghi chú thiết kế
At high input voltage (e.g., 24V) and heavy load, the power dissipation in the buck converters can be significant. Ensure adequate thermal vias and copper pours under the QFN package to maintain junction temperature below 125°C. Refer to the TI datasheet thermal resistance values for the VQFN-24 package.
Place input capacitors close to each buck converter's VIN pins to minimize high-frequency switching noise. Use a 10uF ceramic capacitor for BUCK1 and 4.7uF for BUCK2/BUCK3. Ground the exposed thermal pad to the PCB ground plane with multiple vias.
Do not omit the sequencing between rails; follow the datasheet's recommended power-up ordering to prevent latch-up or misconfiguration. Also, ensure the I2C bus is properly pulled up and the address is set correctly for the selected variant.
