CA-IS3105W is manufacured by chipanalog.

General Description

The CA-IS3105W is a complete isolated DC-DC converter with up to 5kVRMS isolation rating. This device integrates  most of the components needed for an isolated power  supply —switching controller, power switches, transformer,  soft-start, protection circuit etc. — into a single, compact  SOIC package. The result is an efficient and compact fully  integrated solution that is easy to comply with EMI  requirements and makes power-supply design as easy as  possible. Operating over an input voltage range of 4.5V to  5.5V, the CA-IS3105W provides a fixed output voltage of  3.3V, 3.7V, 5V or 5.4V set by pin SEL. Only output, input bypass capacitors, and a pull-up resistor for 3.7V or 5.4V  outputs are needed to finish the design.

The CA-IS3105W device features a unique control scheme,  which can quickly respond to load transient and accurately  regulate the output voltage. The device is capable of  delivering a load up to 650mW output power and offering  soft-start, current limit, short-circuit protection and  thermal shutdown protection features to better enhance  the reliability of the system. The CA-IS3105W includes an  enable input pin (EN). Connect the EN pin to the VINP  input voltage or force this pin high to turn on the DC-DC  converter. Force this pin low to disable the device and  enter shutdown mode. In shutdown mode, the device  stops switching operation with microampere standby  supply current.
