Product Details
LMR33630BQRNXRQ1 – TI Automotive 3A Synchronous Buck Converter
LMR33630BQRNXRQ1 is a Texas Instruments automotive-qualified synchronous step-down DC/DC converter designed for compact and efficient power conversion in rugged automotive and industrial systems. With a 3.8V to 36V input range, 3A output current, 1.4MHz switching frequency, low quiescent current and 12-pin VQFN-HR HotRod™ package, it is suitable for automotive infotainment, telematics, body electronics, 12V/24V rails, industrial controllers and distributed power supplies.
Engineering note: Verify the latest TI datasheet, switching frequency option, PCB layout, EMI margin, thermal path and output voltage setting before production approval.
Component Overview
LMR33630BQRNXRQ1 belongs to the TI LMR33630-Q1 family of automotive synchronous buck converters. It converts a wide automotive or industrial input rail into a stable lower voltage rail for MCUs, sensors, communication modules, display systems and downstream point-of-load regulators.
Circuit Function & Design Role
Converts 12V or 24V vehicle rails into regulated lower voltages for control boards and electronic modules.
Provides up to 3A output current for intermediate rails, system loads and downstream regulators.
HotRod package and parallel input current paths help reduce parasitic effects and switching noise.
Low operating IQ and frequency foldback help improve efficiency in standby and light-load operating modes.

TomatoElec Quality & Supply Notes
As an in-stock independent distributor and electronic components supplier, TomatoElec supports LMR33630BQRNXRQ1 sourcing for engineering samples, production replenishment, urgent replacement and BOM purchasing. For automotive power ICs, correct orderable part number, package type, date code, reel condition and original sourcing are important because the device affects system efficiency, EMI behavior and long-term power reliability.
- Original component sourcing: support sourcing of original Texas Instruments automotive power management ICs.
- Inventory support: help confirm available stock, package condition, date code and shipment schedule.
- Package verification: confirm RNX / VQFN-HR-12 package and large tape-and-reel carrier before shipment.
- BOM matching: verify input range, output current, switching frequency, package, qualification and temperature requirements before approving any substitute.
Replacement & BOM Matching Guidance
LMR33630BQRNXRQ1 should not be replaced only by matching input voltage and output current. Engineers should compare switching frequency, pinout, package, compensation method, output voltage range, current limit, Power Good behavior, EMI performance, thermal resistance and AEC-Q100 qualification.
