The IS6613A is a high-power-density, fully integrated synchronous step-down converter. It incorporates MOSFETs, supports a wide input voltage range, and delivers up to 15A of continuous output current. Its operating frequency spans from 300kHz to 1.5MHz. For maximum efficiency, an external bias can be selected. A differential sensing scheme and internal feedback reference voltage ensure an output voltage tolerance of ±1% across the entire temperature range. The IS6613A features excellent line and load regulation, providing ultra-fast transient response. It employs an energy-saving scheme that significantly enhances light-load efficiency. Additionally, the IS6613A supports PMBus serial interface communication, allowing configuration parameters via pin-strapping and non-volatile memory (NVM). It also offers telemetry readings for IOUT, VOUT, VIN, duty cycle, and temperature. Comprehensive protection features are integrated into the IS6613A, including OCP, NOCP, OVP, UVP, and OTP. Protection responses such as Miss, Latch Off, and Hiccup can be programmed via PMBus.
