Mingjiada Supply And Recycle TI TPSM65620SVCGR 65V 2A Synchronous Buck DC/DC Power Modules

The TPSM65620SVCGR is a 65V input, 2A output synchronous buck DC/DC power module launched by Texas Instruments (TI). It is housed in a 19-pin enhanced HotRod™ QFN-FCMOD (VCG) package and integrates MOSFETs, inductors and compensation networks. It is specifically designed to provide high-density, low-EMI power supply solutions for industrial, communications and test and measurement equipment.

Shenzhen Mingjiada Electronics Co., Ltd. — a long-standing supplier of brand-new, genuine TPSM65620SVCGR modules, whilst also offering high-value buy-back services for TPSM65620SVCGR stock, obsolete stock, surplus stock and discontinued power modules. We provide original manufacturer traceability, rapid quotations and global delivery.

I. TPSM65620SVCGR Product Overview
The TPSM65620SVCGR belongs to TI’s TPSM656x0 family of highly integrated synchronous buck power supply modules (the same series includes the 1A TPSM65610 and the 3A TPSM65630). This device integrates the controller, power transistors, inductor, and input/bootstrap capacitors into a 19-pin QFN-FCMOD package measuring 5.8 mm × 5.2 mm × 2.93 mm. It requires only input and output filter capacitors for operation, significantly reducing PCB footprint and BOM costs.
Based on TI’s ZEN 1 switching technology and incorporating symmetrical pin layout and Dual Random Spread Spectrum (DRSS), the TPSM65620SVCGR easily meets the CISPR 32 Class B radiated emissions standard, making it an ideal choice for space-constrained and EMI-sensitive applications.
