LMR23625CQDDARQ1

LMR23625CQDDARQ1 is a Texas Instruments LMR-series buck regulator IC. It’s a high‑efficiency, fixed‑frequency step‑down DC‑DC converter with an integrated switch, designed to take a relatively high inputVoltage (typical automotive/industrial rails) and regulate it down to a stable, lower output voltage.
Key points:
- Wide input range suitable for automotive/industrial applications
- External feedback network sets the desired output voltage
- Integrated switch with standard control (current‑mode/ PWM) for good transient response
- Enable pin and built‑in protections (e.g., overcurrent/short‑circuit, thermal)
- Small QFN package with exposed pad; CQDDARQ1 denotes the specific package/traceable tape & reel variant
Typical uses:
- Point‑of‑load regulation from 12–24 V rails
- Powering microcontrollers, memory, and other onboard logic in automotive or industrial systems
How to use:
- Connect VIN, GND, set Vout with the resistor divider on FB, and enable the device to start regulation
- Add input/output capacitors and an inductor per the datasheet recommendations
For exact electrical specs, layout guidelines, and the complete feature set, see the TI LMR23625 datasheet and product page.

I can help, but I need details. Do you want TI-only cross-refs or cross-vendor equivalents? Please provide:
- target vendors and packaging (e.g., QFN/DFN)
- key specs (input/output voltage range, current, fixed/adjustable)
With that, I’ll list closest matches from TI, Analog Devices, Onsemi, ST, Maxim, etc. and show cross-reference steps.

Here are the key features of the LMR23625CQDDARQ1:
- Wide input voltage range
- High-efficiency synchronous buck regulator
- Delivers a substantial output current (up to a few amps)
- Adjustable output via external feedback resistors
- Fixed switching frequency in the MHz range (PWM)
- Enable input and programmable soft-start
- Protections: current limit, thermal shutdown, short-circuit protection
- Small footprint/package suitable for space-constrained designs
- Suitable for automotive and general-purpose power applications

- Pin count: 16 pins in a QFN package (with exposed pad).
- Function: A single-output, high-efficiency synchronous buck DC-DC regulator (step-down converter) with integrated high-side and low-side MOSFETs. It uses EN, FB for output voltage, VIN for input, SW (switch node) and BOOT for the gate drive, and GND/thermal pad as references. Suitable for generating core or other rails from a higher input voltage.
