ISL8841AAUZ Description

Short technical summary and product information.

The ISL8841AAUZ is a DC-DC switching controller IC manufactured by Renesas. It is designed for Boost and Flyback topologies, providing a single output transistor driver with positive output configuration and isolation capability. The device operates from a supply voltage range of 9V to 30V and supports a maximum switching frequency of 2MHz. The maximum duty cycle is 48%.

 

Control features include current limiting and frequency control. The device is not a synchronous rectifier and does not support clock synchronization. It is intended for step-up and step-up/step-down applications.

 

The ISL8841AAUZ is specified for an operating temperature range of -40°C to 105°C. It is available in a surface-mount 8-TSSOP or 8-MSOP package (0.118", 3.00mm width). The supplier package is 8-MSOP. The part is RoHS3 compliant (unverified).
