80V bidirectional buck-boost, dual-phase dc-dc controllers enhance performance
RENESAS ISL81801 bidirectional buck-boost and ISL81802 dual buck 80V dc-dc controllers support the extra voltage margin needed for data centre servers, 48V telecom and rugged industrial equipment. ISL81801 device acts like a ‘UPS on a chip’ by enabling bidirectional current flow (forward or reverse) using constant-voltage and constant-current regulation. This allows a battery or super-capacitor to be charged and discharged using a single controller and power path. ISL81801 combines 80V buck-boost switching frequency (600 kHz) with small package (5mm x 5mm) and lets designers create ultra-compact, high-density power solutions.
