概述

Description

TPSM828303ARDSR is a Texas Instruments DC-DC buck regulator in the TPSM power-module family. It’s a compact, fully integrated switch-mode regulator that combines the control circuitry, power switches, and essential support components in a single surface-mount module for easy point-of-load regulation in space-constrained designs.
Key points:
- Integrated regulator module (controller, MOSFETs, inductor, and support parts)
- Converts a higher input voltage to a stable lower output with high efficiency
- Features such as enable, soft-start, protection (overcurrent/short-circuit, overtemperature), and good transient response
- Suitable for pulling down voltage rails for processors, FPGAs, and other electronics in compact systems
- Package and packaging variant (ARD/SR) denote the specific form-factor and tape/reel options
For exact specs (input range, output voltage, max current, efficiency, switching frequency, pinout, and package details), refer to the TPSM828303ARDSR datasheet and TI product page.

Features

Key features of TPSM828303ARDSR (TI Simple Switcher module):
- 3-A continuous output current (step-down regulator)
- Automotive-grade variant (A-grade) with wide operating range
- Input voltage range: broad (suitable for automotive systems); typical up to 42 V
- Fixed output: 3.3 V (TPSM828303 variant)
- Synchronous buck topology with integrated MOSFETs
- High efficiency (up to ≈95% in typical conditions)
- Compact, integrated power module suitable for surface mounting
- Enable input and Power-Good status
- Protections: overcurrent/short-circuit, thermal shutdown, UVLO
- RoHS-compliant; tape-and-reel packaging for automated assembly
Note: Some specifications can vary by revision or lot; always consult the latest datasheet for exact numbers.

Pinout

- Pin count: 8 pins
- Function: 3-A synchronous buck (step-down) DC-DC converter with integrated high-side and low-side MOSFETs, including EN and FB pins for output voltage control (fixed/adjustable output).

Manufacturer

The TPSM828303ARDSR is manufactured by Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures integrated circuits, specializing in analog and mixed-signal ICs, power management, and embedded processing solutions.

Equivalent

I don’t have live database access to confirm direct drop‑in equivalents for TPSM828303ARDSR. Typical substitutes are other TPSM8283xx family modules or similar integrated buck modules from Murata, RECOM or Coopermation—only after matching Vin, Vout, max load, package and pinout. Use TI’s parametric search or distributor cross‑references (Digi‑Key, Mouser, Octopart). Share the TPSM828303 datasheet specs and I’ll recommend specific equivalent parts.
