TPSM365R6RDNR-IC; CONVERTER DC-DC NON-ISOLATED POL MODULE 1-CHANNEL I/P 3-65V O/P 1-13V 60 — BOLTON SKU 67796.
About the TPSM365R6RDNR DC-DC Module, 3-65V In, 600mA
The TPSM365R6 is a non-isolated synchronous step-down power module from Texas Instruments, supplied with the switching regulator and its inductor integrated in one package so that the external network reduces to input and output capacitors and the feedback divider. It accepts a 3 V to 65 V input with transient capability quoted to 70 V, which is what allows a single design to sit behind 12 V, 24 V and 48 V distribution without a front-end pre-regulator. The adjustable version covers a 1 V to 13 V output; fixed 3.3 V and 5 V options exist in the same family. Output current is 0.6 A, and the switching frequency is adjustable from 200 kHz to 2.2 MHz so the converter can be moved away from a sensitive band or traded against solution size. The RDN order suffix denotes the QFN-FCMOD package measuring 4.5 mm × 3.5 mm × 2 mm, and the operating temperature range is −40 °C to +125 °C.

Typical applications
A wide-input module of this kind is used to generate local low-current rails directly from an unregulated bus: housekeeping and bias supplies, sensor and instrumentation nodes, always-on supervisory rails, and gate-driver or auxiliary supplies within larger converters. The 65 V input ceiling suits 24 V and 48 V industrial and vehicle-style distribution where load dump and surge push the rail well above nominal. Integrating the inductor shortens the design and layout effort and keeps the switching loop area fixed, which is often the reason a module is chosen over a discrete regulator at this current level.
