Product Details

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, resistors 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, this device provides a fixed output voltage of 3.3V, 3.7V, 5V or 5.4V set by pin SEL. The CA-IS3105W 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, and thermal protection features to better enhance the reliability of the system.

The CA-IS3105W is available in wide-body SOIC16 package and operates over -40°C to +125°C temperature range.
