The Texas Instruments PT78ST105H is a non-isolated point-of-load (PoL) module from the PT78ST100 series. It provides a regulated 5V output at up to 1.5A from a wide input voltage range of 9V to 38V. The module achieves typical efficiency of 85% at 10V input and 1A load, and operates at a switching frequency of 650 kHz.
Key electrical characteristics include output ripple of 65 mVpp, line regulation of ±0.2%, load regulation of ±0.1%, and transient response of 100 µs for a 50% load change. The module includes over-temperature protection (OTP) and short-circuit protection (SCP) with a typical short-circuit current of 3.5 Apk.
The PT78ST105H is housed in a 3-SIP module with through-hole, right-angle mounting. Dimensions are 23.9 mm x 22.9 mm x 7.9 mm and weight is 6.5 g. It is designed for commercial ITE applications and operates over a temperature range of -40°C to 85°C.
