TPSM53602/3/4 2 A, 3 A, and 4 A Step-Down Power Modules
Texas Instruments' 36 V synchronous DC/DC modules come in a small RLF QFN package with a simple footprint
Texas Instruments' TPSM53602, TPSM53603, and TPSM53604 power modules are highly integrated 2 A, 3 A, and 4 A (respectively) power solutions that combine a 36 V input, step-down DC/DC converter with power MOSFETs, a shielded inductor, and passives in a thermally-enhanced QFN package. The 5 mm x 5.5 mm x 4 mm, 15-pin QFN package uses routable lead-frame (RFL) technology for enhanced thermal performance, a small footprint, and low EMI. The package footprint allows access to the pins from the perimeter and features a single large thermal pad for a simple layout and easy handling in manufacturing.
The total solution requires as few as four external components and eliminates the loop compensation and magnetics part selection from the design process. The full feature set includes power good, programmable UVLO, pre-bias startup, overcurrent (OCP), and overtemperature protection (OTP), making the TPSM53602, TPSM53603, and TPSM53604 excellent devices for powering a wide range of applications.
