Automotive 1.5W Complete Isolated Power Supply
The CA-IS3115AW-Q1 is a family of complete isolated DCDC converters with up to 5kVRMS isolation rating. These devices integrate most of the components needed for anisolated power supply —switching controller, powerswitches, transformer, soft-start, protection circuit etc. —into a single, compact SOIC package. The result is anefficient and compact fully integrated solution that is easyto comply with EMI requirements and makes power-supplyisolation design as easy as possible. Operating over aninput voltage range of 4.5V to 5.5V, the CA-IS3115AW-Q1devices provide a fixed output voltage of 3.3V, 3.7V, 5V or5.4V set by pin SEL. 3.7V and 5.4V output options provideheadroom voltage to power an LDO. Only output, inputbypass capacitors, and a pull-up resistor for 3.7V or 5.4Voutputs are needed to finish the design.
The CA-IS3115AW-Q1 devices feature a unique controlscheme, which can quickly respond to load transient andaccurately regulate the output voltage. The devices arecapable of delivering a load up to 1.5W output power andoffering soft-start, current limit, short-circuit protectionand thermal shutdown protection features to betterenhance the reliability of the system. The CA-IS3115AW-Q1devices include an enable input pin (EN). Connect the ENpin to the VINP input voltage or force this pin high to turnon the DC-DC converter. Force this pin low to disable thedevice and enter shutdown mode. In shutdown mode, thedevice stops switching operation with microamperestandby supply current.
The CA-IS3115AW-Q1 devices are available in wide-bodySOIC16 package with creepage and clearance > 8mm, andoperate over -40°C to +125°C temperature range.
