Buck-Boost Demo Board - ISL8117ADEMO4Z

By Design Library |

The ISL8117ADEMO4Z demo board features the ISL8117A synchronous step-down controller that generate Point-of-Load (POL) voltage rails and bias voltage rails for a wide variety of applications in industrial and general purpose segments. The device features a wide input range 6.5V to 42V and programmable soft-start considering it is small and compact design with high efficiency and high power density.

ISL8117ADEMO4Z uses ISL8117A IC as the controller and it serves also the main component. Other than the controller, the switching power components and small signal components also helps in the operation. The ISL8117A is a 60V high voltage synchronous buck controller that offers external soft-start and independent enable functions and integrates UV/OV/OC/OT protection. Its current mode control architecture and internal compensation network keep peripheral component count minimal. Programmable switching frequency ranging from 100kHz to 2MHz helps to optimize inductor size while the strong gate driver delivers up to 30A for the  buck output.

This demo board is suitable for product development related to industrial equipments, PLC, and some factory automation. It is also applicable in telecommunication considering this synchronous step-down PWM controller is needed.
