TPSM65610 vs TPSM65620 vs TPSM65630 | 65V Power Modules
Series: TPSM656x0
Topology: Synchronous step-down buck
Package/Case: 19-pin VCG QFN-FCMOD
Package Size: 5.2mm × 5.8mm × 2.93mm
Description: 65V synchronous buck power modules with integrated inductor, selectable output voltage and low-EMI switching technology.
The Texas Instruments TPSM656x0 family provides compact, non-isolated DC/DC conversion for industrial systems operating from wide input-voltage rails.
The TPSM65610, TPSM65620 and TPSM65630 share the same 3V to 65V input range, 1V to 24V adjustable output range and 19-pin enhanced HotRod™ QFN package. The main difference is maximum output current: 1A, 2A or 3A.

Frequently Asked Questions
What is the main difference between TPSM65610, TPSM65620 and TPSM65630?
The main difference is maximum output current. The TPSM65610 supports 1A, the TPSM65620 supports 2A and the TPSM65630 supports 3A.
Are the three modules pin-compatible?
They share the same 19-pin VCG QFN-FCMOD package and common pin arrangement, simplifying the creation of a scalable PCB platform. External components, thermal performance and current limits should still be reviewed when changing models.
Can these modules operate from a 48V bus?
Yes. All three support a recommended input voltage up to 65V. Surge protection may be necessary if a nominal 48V system can exceed that limit during transient conditions.
Do all versions support spread spectrum?
The TPSM65610SVCGR, TPSM65620SVCGR and TPSM65630SVCGR support spread spectrum. The TPSM65630VCGR is a 3A version without spread-spectrum modulation.
Which model should replace a 1A module when more current is needed?
The TPSM65620 is suitable for loads up to 2A, while the TPSM65630 supports loads up to 3A. The final choice should include sufficient current and thermal margin for startup and transient conditions.
