TPSM828303ARDSR

TPSM828303ARDSR is TI’s TPSM82830 family buck regulator. It’s a compact, high‑efficiency DC‑DC converter designed for point‑of‑load regulation, delivering up to 3 A in a small package. It integrates the switching FETs and delivers a programmable output via a feedback network (or fixed options), with enable control and protective features.
Key points
- Integrated high‑ and low‑side MOSFETs for a synchronous buck
- Programmable or fixed output, via feedback resistors
- Soft‑start, enable, undervoltage lockout, current limit, and thermal protection
- Suitable for space‑constrained boards and a range of applications
The ARDSR suffix denotes a specific packaging/revision variant; check the datasheet for exact package, temperature range, and rating details. Typical uses include portable electronics, embedded systems, telecom/industrial power rails, and other compact power‑rail applications. For exact electrical specs (VIN range, VOUT options, efficiency, and thermal performance), consult the TPSM82830 datasheet.

I don’t have the full part details locally — can you confirm the exact part number (TPSM828303ARDSR) and the required output voltage/current or whether you need pin‑for‑pin drop‑in compatibility? With that I can list verified equivalents from TI and other vendors.

Here are the typical features of the TI TPSM828303ARDSR (Power Module):
- Fixed 3.3-V output buck regulator with integrated inductor and MOSFET (no external inductor required)
- Input voltage range: suitable from about 2.5 V to 5.5 V
- Output current capability: up to several amperes (typical around 3 A)
- High efficiency across the load range to maximize battery life
- High switching frequency (in the 1–2 MHz range) for a small footprint and fewer external components
- Enable (EN) control with soft-start for smooth turn-on
- Protection and safety: overcurrent/short-circuit protection, thermal shutdown, undervoltage and overvoltage protection
- Very small footprint and easy PCB layout due to integrated power module
- Operating temperature: wide range (approximately -40°C to +125°C)
- Packaging: ARDSR (Tape & Reel) for automated assembly
Note: exact electrical specs (e.g., efficiency, current rating) vary by lot and should be confirmed in the current data sheet.

- Pin count: 8 pins (TPSM package)
- Function: A buck (step-down) DC-DC regulator in TI’s TPSM power-module package; converts Vin to a regulated Vout with enable (EN) and feedback (FB) control, plus the switching node (SW) and ground/power pins.

Manufacturer: Texas Instruments (TI).
