LMR23630QDRRRQ1

LMR23630QDRRRQ1 is a Texas Instruments automotive-grade buck regulator. It is designed to convert a higher automotive-style input to a lower, stable output for onboard electronics (MCUs, sensors, peripherals) in cars and machines. Key points:
- Wide input range suitable for automotive environments; rugged with protections (overcurrent, UVLO, thermal shutdown, short-circuit protection).
- High efficiency and compact package for space-constrained designs.
- Programmable output via feedback network; features typical buck regulator controls (soft-start, enable, fault/power-good signaling in many variants).
- Automotive-grade version (suffix indicates AEC-Q compliant) and specific packaging/revision (QDRRRQ1).
Applications include automotive ECUs, infotainment/telemetry subsystems, sensors, and other 12V automotive power rails. For exact electrical specs (input range, output voltage options, switching frequency, pinout, and package), consult the TI datasheet and product page.

Here are the key features of LMR23630QDRRRQ1 (automotive-grade):
- 3-A continuous output current, buck regulator
- Wide input range up to 40 V (suitable for automotive and transients)
- Synchronous buck with integrated high- and low-side MOSFETs for high efficiency
- Output voltage adjustable via external resistor network (0.8 V reference)
- Fixed-frequency PWM control with current-mode regulation; light-load mode for efficiency
- Enable input with undervoltage lockout; soft-start control
- Protective functions: overcurrent/short-circuit protection, thermal shutdown, input/output protections
- Power-good/power-down signaling typically available
- Automotive-grade, AEC-Q100 qualified
- Available in a small QFN package with exposed pad (robust thermal performance)
Notes: For exact electricals (Vout range, switching freq, quiescent current, packaging details), consult the latest TI datasheet.

Pin count: 10 pins (QFN/VQFN 3x3 package, LMR23630QDRRRQ1).
Function: a high-efficiency 3-A step-down (buck) regulator with an integrated high-side switch. VIN feeds the regulator, SW/LX drives the external inductor, and output is sensed via FB for regulation. Includes enable (EN), soft-start/trequency set (RT/SS), and power-good (PG) features.

Manufacturer: Texas Instruments Incorporated (TI).
What kind of company: TI is a global American semiconductor company that designs and manufactures analog and embedded processing integrated circuits, including power-management devices used in automotive, industrial, consumer, and computing applications.

LM23630QDRRRQ1 is a high-efficiency wide-input (up to 30V) buck regulator. Typical application areas include:
- Automotive electronics: powering ECUs, infotainment, instrument clusters from 12–24V rails
- Industrial/automation: supply rails for microcontrollers, FPGAs, DSPs, sensors
- Networking/communication: base stations, routers, switches
- Computing/embedded: CPU/GPU core rails, memory, ASICs in motherboards and SBCs
- Consumer electronics: compact DC-DC power modules for portable/standalone devices
In short, any system needing a compact, efficient 30V-input step-down regulator for core/peripheral rails.

It is a 16‑pin QFN package (3.0 mm × 3.0 mm) with an exposed pad (EP).
