Chipanalog New Product Release – CA-IS3105W
CA-IS3105W Complete Isolated DC-DC Converter/Isolated Error Amplifier
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 to5.5V, the CA-IS3105W provides a fixed output voltage of3.3V, 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 VIN Pin put 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.
The CA-IS3105W is available in wide-body SOIC16 package and operates over -40°C to +125°C temperature range.
