- Buyers Guide
Texas Instruments Inc. (TI) introduced the industry’s smallest monolithic point-of-load (POL) DC/DC converters for harsh environments, including radiation tolerant, geological, heavy industrial, and oil and gas applications. The 6.3 V, 6-A TPS50601 and the 6.3 V, 3-A TPS50301 are synchronous step- down converters optimized for small form factor designs.
The devices’ current mode control, high switching frequency, and integration of the high- and low-side MOSFETs slash board space by 50 percent compared to other solutions, reducing the size of equipment needed for tight spaces, such as down-hole drilling. For more information or to order samples and an evaluation module (EVM), see www.ti.com/tps50601-pr.
Key features and benefits of the TPS50601 and the TPS50301:
The TPS50601 and the TPS50301 are sampling now in a 20-pin thermally enhanced dual in-line ceramic flatpack. Please contact firstname.lastname@example.org for suggested retail price of the TPS50601, and email@example.com for suggested retail price of the TPS50301.
The TPS50601 is supported by single- and dual-configured EVMs. The dual TPS50601SPEVM-D provides high efficiency and high reliability due to reduced stress on the components. The single TPS50601SPEVM-S implements split-input power rails with separate voltage inputs for power stage and control circuitry. Suggested retail price is US$499 for the single EVM and US$599 for the dual EVM.
The harsh environment engineering model (EM), TPS50601HKHMPR, is a TPS50601 prototype for initial evaluation for harsh environment customers. The model provides the same functionality and footprint as the TPS50601, but at a reduced cost and for evaluation only.
A small form factor reference design of approximately 1 inch by 1 inch is available. It features optimal layout, high efficiency, design calculations, transient response, and information on the device design and test results.
Engineers can ask questions and get answers from TI experts on the High Reliability Forum in the TI E2E™ Community.
