The STR-L472 from Sanken is a power integrated circuit (IC) specifically designed for quasi-resonant type switching power supplies. It incorporates a high-voltage power MOSFET and a controller IC within a low-height SIP-10 package, facilitating designs with sufficient creepage isolation between high and low voltage terminals.
Key electrical features include a minimum drain-source breakdown voltage (VDSS) of 900V and a maximum drain-source on-resistance (RDS(ON)) of 7.7 Ohms. The device operates with a Flyback topology and provides isolated output, supporting power up to 74W. It also includes various protection features such as Overcurrent Protection (OCP), Pulse-by-Pulse Overload Protection (OLP), and Thermal Shutdown Protection (TSD).
The STR-L400 series, including the STR-L472, is recommended for systems requiring low-profile designs and adequate clearance and creepage isolation. The package dimensions are optimized for height over PCB (< 12mm) with a straight lead pitch of 2.54mm. The IC supports quasi-resonant operation for high efficiency and low noise.
Applications for the STR-L472 include switching power supplies for standby power, home appliances (white goods), digital consumer equipment, OA equipment, industrial machines, and communication devices.
