Texas Instruments Debuts TPS50601, TPS50301 monolithic POL DC/DC Converters

Texas Instruments (TI) TPS50601 and TPS50301 monolithic point-of-load (POL) DC/DC converters

Texas Instruments announced their TPS50601 and TPS50301 monolithic point-of-load (POL) DC/DC converters. The TI devices are synchronous step-down converters optimized for small form factor designs. The 6.3-V, 6-A TPS50601 and the 6.3-V, 3-A TPS50301 are sampling now in a 20-pin thermally enhanced dual in-line ceramic flatpack. They are ideal for radiation tolerant, geological, heavy industrial, and oil and gas applications.

The TI TPS50601 and the TPS50301 feature current mode control, high switching frequency, and integration of the high- and low-side MOSFETs. The Texas Instruments devices reduce board space by 50% compared to other solutions.
