TPS53820RWZR

TPS53820RWZR is a Texas Instruments high-efficiency, step-down (buck) DC-DC converter. It is designed for compact point‑of‑load regulation in battery-powered and portable electronics.
Key points
- Output: up to about 1 A with external feedback to set Vout.
- Input range: wide (typical multiple-volt range suitable for battery or 5 V systems).
- Operation: fixed-frequency PWM switching with enable, soft-start, and built‑in protections (overcurrent, thermal shutdown).
- Package: 6-pin WSON in the RWZR tape-and-reel/RoHS family; compact footprint with low external component count.
- Applications: power rails for microprocessors, ASICs, FPGAs, embedded systems.
Usage basics
- Connect Vin and GND, place an inductor and capacitors as per the datasheet.
- Use a resistor divider on FB to set the desired output voltage.
- Drive EN high to enable; monitor PGOOD if provided.
Note: exact Vout range, switching frequency, and protection thresholds are defined in the datasheet; the RWZR suffix indicates RoHS-compliant, wettable-flank packaging in reel form.

TPS53820RWZR features (highlights; exact specs in the datasheet):
- 8-pin RW package (compact, surface-mount)
- Buck (step-down) regulator with integrated switch
- Enable input for power on/off control
- Adjustable output via external resistor divider
- Soft-start to limit inrush
- Power protection: overcurrent/short-circuit protection and thermal shutdown
- Undervoltage lockout for safe start-up
- High efficiency over load range
- Minimal external components required (inductor, input/output caps, resistors)
- Suitable for broad applications (industrial/automotive, etc.)
Note: For precise input voltage range, output range, switching frequency, and protection details, please consult the TPS53820 datasheet.

TPS53820RWZR uses an 8‑pin WSON package (3.0 × 3.0 mm, 0.8 mm pitch), RoHS-compliant; available in tape-and-reel.

- Pin count: 20 pins (VQFN-20 package).
- Function: Dual synchronous buck DC-DC regulator (two-output step-down converter) with enable and status features.

- Manufacturer: Texas Instruments (TI)
- What kind of company: TI is an American multinational semiconductor company that designs, manufactures, and sells analog and embedded processing ICs. Headquartered in Dallas, Texas, it is one of the world’s largest semiconductor makers.
