The Texas Instruments PT78ST212V is a 3-terminal Integrated Switching Regulator (ISR) from the PT78ST200 series, designed as a non-isolated Point-of-Load (PoL) module. It delivers a regulated 12V output with a continuous current capability of 2A and a surge current rating of 3A, making it suitable for powering inductive loads such as disk drive motors.
Key electrical specifications include a wide input voltage range of 16V to 28V, typical efficiency of 87% at full load, and a switching frequency of 1 MHz. The module offers tight output voltage regulation with a tolerance of ±2% and provides line and load regulation of ±0.8% and ±0.4%, respectively. Protection features include over-temperature protection (OTP) and short-circuit protection (SCP).
The PT78ST212V is packaged in a compact 3-SIP (Single In-line Package) module with a through-hole mounting style. Its dimensions are 25.7 mm in length, 9.7 mm in width, and 24.9 mm in height, with a weight of 11 grams. The module is designed for commercial ITE applications and operates over a temperature range of -40°C to +65°C.
The output voltage is 12 V.
The maximum output current is 2 A.
The input voltage range is 16 V to 28 V.
