LMR33620CRNXR

LMR33620CRNXR is Texas Instruments’ Simple Switcher synchronous buck regulator. It integrates the high- and low-side MOSFETs for a compact, high-efficiency step-down converter suitable for automotive, industrial, and consumer electronics.
Key points:
- Synchronous buck regulator with external inductor and input/output capacitors
- Wide input range and adjustable output via feedback network (fixed-output options available)
- Enable pin, soft-start, and protections (overcurrent/short-circuit, undervoltage lockout, thermal shutdown)
- High efficiency with fast transient response
- Packaging suffix XR and RoHS-compliant options; suitable for tape-and-reel supply
Typical uses: point-of-load supplies for processors, FPGAs/ASICs, embedded systems, automotive electronics.
For exact electrical specs (input range, output voltage options, switching frequency, inductor value) and pinout, consult the TI LMR33620CRNXR datasheet and product page.

Here are the key features of the TI LMR33620CRNXR:
- Wide input range: 4.5 V to 60 V
- Output current: up to ~2 A
- Switching frequency: ≈ 2 MHz (typical)
- High efficiency: up to about 95% (depends on conditions)
- Flexible output: adjustable via external feedback or fixed options
- Internal high-side switch with protections; requires external inductor and input/output capacitors
- Enable pin with undervoltage lockout
- Protection features: overcurrent (current limit) and thermal shutdown
- Soft-start to control inrush and output ramp
- Small, RoHS-compliant QFN package (CRNXR variant)
Note: External passive components (inductor, capacitors, feedback resistors) are required for proper operation.
