TPSM33615FRDNR

The TPSM33615FRDNR is a Texas Instruments Power Module (TPSM) that combines high-side/low-side MOSFETs and a switching regulator controller in a compact TPSM package. It is designed for synchronous buck DC-DC conversion, enabling a small, efficient point-of-load power regulator with built-in protection features.
Key points
- Integration: dual MOSFETs plus controller for a synchronous buck stage; reduces BOM and PCB area.
- Protections: overcurrent, overtemperature, undervoltage/UVLO, soft-start and fault handling typical of TI power modules.
- Applications: automotive and industrial power rails, VRMs, and other high-density point-of-load applications.
- External network: requires external feedback resistors and an inductor (and input/output decoupling per datasheet) for setting output voltage and ensuring stable operation.
- Resources: consult the TI datasheet and reference designs for pinout, layout tips, and application notes.
In short, TPSM33615FRDNR is a compact, rugged, high-efficiency power-module solution for integrated buck regulation in demanding environments.

TPSM33615FRDNR features (concise):
- High-efficiency, synchronous buck regulator with integrated power MOSFETs.
- Very small package (TPSM family) with exposed pad; RoHS-compliant; Tape & Reel (FRDNR).
- Wide input voltage range suitable for common 2.7–5.5 V rails (battery and 5V systems).
- Adjustable output voltage via external feedback network.
- Fixed-frequency, current-mode PWM for fast transient response.
- Enable input with undervoltage lockout and controllable soft-start.
- Robust protection: overcurrent/short-circuit protection, overtemperature shutdown, UVLO.

- Ideal for compact multi-rail power designs in mobile/IoT applications.

I don’t have live access to TI’s datasheets. Please allow me to look up the TPSM33615FRDNR datasheet (or paste it here) and I’ll quickly tell you the exact package type and package code.

- Pin count: 8 pins (QFN package)
- Function: Single-channel high-efficiency buck (step-down) DC-DC regulator with integrated MOSFETs in TI’s TPSM33615 family. It uses VIN, LX (switch node), GND, FB (feedback), EN (enable), plus two pins reserved/not connected and an exposed thermal pad for heat sinking.

Manufacturer: Texas Instruments Incorporated (TI).
What kind of company: TI is an American semiconductor company that designs and manufactures analog and embedded processing integrated circuits—including power-management ICs, microcontrollers, and mixed-signal devices—headquartered in Dallas, Texas.

TPSM33615FRDNR is a high-side load switch with protection features. Application areas include automotive power distribution and protection, industrial equipment, and consumer electronics. Typical uses: automotive body electronics and gateways; hot-swap/backplane protection in telecom/industrial systems; LED backlighting and display rails; motor/actuator power paths; and general power-path switching in battery-powered devices.

There are no widely published exact drop‑in equivalents for TI’s TPSM33615FRDNR. To replace it, pick a synchronous buck power module with the same input range, adjustable output, 1.5 A (or higher) rating, and matching package/pinout. Consider TI’s nearby TPSM family parts or similar third‑party PMIC modules from Analog Devices, Microchip/MPS, or Murata—verify electrical specs, footprint, thermal and BOM differences.
