Introduction

AI Translation

CA-IS3115X is a DC-DC converter IC supporting 2.5/5.0kV_RMS isolation voltage, integrating an on-chip transformer to efficiently deliver 1.5W of power to the secondary-side output. The device employs a proprietary control architecture for fast load transient response and precise output voltage regulation. CA-IS3115X can replace traditional isolated power supply solutions built with discrete components, offering a smaller footprint with full galvanic isolation.

CA-IS3115X integrates multiple protection features including soft-start, short-circuit protection, and over-temperature protection to enhance system reliability. CA-IS3115X features an EN pin; when EN is driven low, the output voltage drops to zero, with only microamp-level standby input current drawn from the supply.

CA-IS3115X supports four selectable output voltages via the SEL pin: 5V, 3.3V, 5.4V, and 3.7V, with LDO post-regulation support to accommodate diverse voltage requirements. CA-IS3115X is available in a 16-pin wide-body SOIC package with creepage and clearance distances greater than 8mm, a maximum withstand voltage of 5kV_RMS, and an operating temperature range of -40°C to 125°C.
