TPS650362-Q1 - Automotive 35V PMIC | Texas Instruments
MPN: TPS650362-Q1 ✓ Hoạt độngTPS650362-Q1 Tóm tắt
A PMIC (Power Management IC) is a form of integrated circuit that manages the power requirements of a host system, providing multiple regulated voltages from a single input source. The TPS650362-Q1 fits into the power management hierarchy as a highly integrated PMIC → automotive power management IC → automotive semiconductor, consolidating multiple discrete regulators into one solution to reduce board space, cost, and system complexity.
Key features include three independent buck converters for high-efficiency step-down conversion, one LDO for noise-sensitive analog rails, and an input voltage capability of 35V on BUCK1. The device's ASIL-B capability supports functional safety requirements in automotive safety-critical systems. Its integrated architecture reduces external component count and enables a compact camera module design.
In terms of technical depth, the TPS650362-Q1 utilizes TI's advanced process technology to combine high-voltage input capabilities with efficient switching converters. The buck converters likely operate at high switching frequencies to minimize magnetic component sizes, while the LDO provides low-noise output for sensitive analog circuits. The device is designed to meet stringent automotive reliability standards.
Typical applications for the TPS650362-Q1 include automotive camera modules, radar systems, and MCU power supplies. Its 35V input capability allows direct connection to filtered 12V automotive power, while ASIL-B qualification makes it suitable for safety-relevant functions.
When designing with this PMIC, ensure proper input decoupling for the high-voltage buck converter and follow recommended layout practices to minimize switching noise. Verify the complete pinout and package specifications from the official datasheet before production.

Ghi chú thiết kế
For the TPS650362-Q1, place a 10uF or larger ceramic capacitor with a 50V rating close to the BUCK1 input to handle 35V transients. Also add a 0.1uF capacitor to suppress high-frequency noise. Ensure adequate bulk capacitance on the battery rail.
The PMIC handles multiple regulators, so consider thermal dissipation. Use a 2oz copper pour on the PCB and via stitching to the ground plane to keep junction temperatures low in automotive environments. Verify operating junction temperature limits from the datasheet.
Verify the power sequencing requirements for the three buck converters and LDO. Some MCUs require specific rail order. Consult the datasheet for the recommended start-up sequence to avoid latch-up. Ensure proper decoupling on all outputs.
