PT78ST115S Description

Short technical summary and product information.

The Texas Instruments PT78ST115S is a Non-Isolated Point-of-Load (PoL) Module DC DC Converter from the PT78ST100 series. It provides a regulated 15V output with a maximum output current of 1.5A. The device features a wide input voltage range, with typical values for 12V output spanning 16V to 38V. It offers excellent line and load regulation, with typical line regulation of ±0.2% and load regulation of ±0.1%. The switching frequency is typically 650 kHz.

 

The module includes over-temperature protection and short-circuit protection for reliable operation. It is designed for surface mount assembly in a compact 3-SMD module package measuring 23.9mm x 22.9mm x 8.6mm and weighing 6.5g. The operating temperature range is -40°C to +85°C, with a storage temperature range of -40°C to +125°C. Typical applications include ITE (commercial) equipment.
