(1) Custom temperature ranges available(2) These units are intended for engineering evaluation only. They are processed to a non-compliant flow (that is no burn-in, and so forth) and are tested to temperature rating of 25°C only. These units are not suitable for qualification, production, radiation testing or flight use. Parts are not warranted for performance on full MIL specified temperature range of –55°C to 125°C or operating life.

The TPS50301-HT is a 6.3-V, 3-A and the TPS50601-SP is a 6.3-V, 6-A synchronous step-down converter, which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. Further space savings are achieved through current mode control, which reduces component count, and a high switching frequency, reducing the inductor's footprint. The devices are offered in a thermally enhanced 20-pin ceramic, dual in-line flatpack package.
