ISL78234EVAL2Z

ISL78234EVAL2Z is an evaluation board for 4A synchronous buck ISL78234. This is used to demonstrate the performance of the ISL78234 low quiescent current, high efficiency synchronous buck regulators. The evaluation board is intended for use by customers with requirements for point-of-load automotive applications with 2.7V to 5.5V input supply voltage. The ISL78234 is offered in a 5 x 5mm 16 Ld wettable flank QFN (WFQFN) package with 0.9mm maximum height. Application includes DC/DC POL modules, μC/µP, FPGA and DSP power, video processor/SOC power, Li-ion battery powered devices, automotive infotainment power.
