STR-V152

The Sanken STR-V152 is an integrated circuit designed for off-line switching power supply applications. It combines a power MOSFET and a controller IC with current-mode and Pulse Ratio Control (PRC) for efficient operation.

Key electrical characteristics include a minimum breakdown voltage of 650V and a maximum on-resistance of 2.8Ω. The device features a fixed off-time of typically 8µs, contributing to stable performance. It also incorporates an auto-standby function, achieving low power consumption with input power at no load less than 40mW.

This regulator is housed in a low-profile SIP8L package with a 2.54 pitch and straight lead pins. It offers a creeping distance of 4mm or longer between high and low voltage pins on the PCB, enhancing safety. The package height from the PCB is 12mm or less.

The STR-V152 includes built-in protection functions such as Overcurrent Protection (OCP), Overvoltage Protection (OVP), Overload Protection (OLP), and Thermal Shutdown (TSD). These features ensure reliable operation in applications like stand-by power supplies, white goods, office automation equipment, industrial equipment, and communication equipment.
