Triple output synchronous step-down controller regulates three buck outputs from a 4.5 V to 38 V input supply. The controller uses constant-frequency current-mode control with RSENSE or inductor DCR current sensing and supports differential output sensing. Output regulation is based on a 0.6 V reference, with adjustable outputs down to 0.6 V. The EUH package is a 32-lead 5 mm by 5 mm QFN intended for extended-temperature operation.
