regulatedSIPfor railway applications

Product overview
The TPS-H7805500 is a DC/DC converter module in the TPS-H78500 series. It is supplied in an industrial SIP-3 package and is designed for stable operation in harsh environments with an operating temperature range of -40°C to +85°C. The series offers high efficiency (up to 95%); this model typically achieves ~90% efficiency. It supports negative output configurations, includes built-in output short-circuit protection, is RoHS compliant and is specified with an MTBF of 2000 kh. Typical series outputs: 3.3V, 5V, 9V, 12V, 15V. TPS-H7805500 provides 5V output at 0–500mA (2.5W).
