ISL8102IRZ is a DC to DC switching controller that helps power optimized and simplified power conversion. It provides manufacturers with highly efficient, low quiescent current, high power density, point-of-load power regulators. The switch controller enables the fast and simple design of DC to DC converter solutions in applications including servers, portable computers, portable medical devices, and high-end compute clusters.

ISL8102IRZ includes onboard analog and digital components for controlling a wide range of DC-DC power converters with voltages from 0.6V up to 24V. This high-performance IC features a 0.5V to 6V input voltage range with programmable frequency, on/off time ratios, and undervoltage lockout. Additionally, the ISL8102IRZ features programmable soft-start and is optimized for low EMI.

ISL8102IRZ Working Principle:

The ISL8102IRZ is a monolithic voltage controller circuit with a built-in low-dropout linear series regulator. It implements a cycle-by-cycle current limit and a protected digital current-limit setting circuit. By applying a PWM signal to an external optocoupler and output transistor, the ISL8102IRZ regulates the output voltage accurately. The current limit is adjusted by either an external resistor or a digital current limit setting. The converter also provides short-circuit protection, open shutdown and low-voltage output protection.
