The ISL81334IAZ is a synchronous buck controller from Renesas. It is a high-performance, monolithic, pulse-width modulation (PWM) controller with integrated high-speed low-side power MOSFETs. The ISL81334IAZ is specifically designed to provide cost-effective and reliable power solutions in a small size, while delivering high-performance and efficient power conversion. The device uses an innovative current-mode method that allows for uniform switching frequencies and low output voltage ripple. It provides adjustable output voltage, worst-case current limit protection and excellent line and load transient response. The device is designed to be used with Renesas’ devices and circuits, such as the ISL81333 or ISL91333.
