The Texas Instruments PT78ST112H is a non-isolated point-of-load (PoL) module from the PT78ST100 series of wide-input range, 3-terminal integrated switching regulators. It delivers a regulated 12V output at up to 1.5A from an input voltage range of 16V to 38V. The module achieves a typical efficiency of 90% at full load (Vin=17V, Io=1A) and features excellent line and load regulation (±0.4% and ±0.2% maximum, respectively).
Output ripple and noise is typically 90mVpp (Vin=16V, Io=1.5A), and the switching frequency ranges from 600kHz to 700kHz. The device includes over-temperature protection (OTP) and short-circuit protection (SCP) for reliable operation. The output voltage tolerance is ±2% maximum over the input voltage range at 1.5A load.
The PT78ST112H is housed in a 3-SIP module with a through-hole, right-angle mounting configuration. Its compact dimensions are 23.9mm x 22.9mm x 7.9mm and it weighs 6.5g. The operating temperature range is -40°C to +85°C, with a typical thermal resistance of 45°C/W in free air convection (40-60 LFM). This module is suitable for commercial ITE (Information Technology Equipment) applications.
