STMicroelectronics L6590 Fully Integrated Power Supply Datasheet

The L6590 is a monolithic switching regulator designed in BCD OFF-LINE technology, able to operate with wide range input voltage and to deliver up to 15W output power. The internal power switch is a lateral power MOSFET with a typical RDS(on) of 13Ω and a V(BR)DSS of 700V minimum. The device can work with secondary feedback and a 2.5V±2% internal reference, in addition to a high gain error amplifier, makes possible also the implementation of other types of converters.
