XR77103ELBTR-A0R5

The XR77103-A0R5 and XR77103-A1R0 from Exar are 3-output, synchronous buck regulators with an input-voltage range of 4.5 V to 14 V. Both high-side and low-side MOSFETs are integrated to provide a low component count, highly efficient solution. Both have a 1% accurate, 0.8 V feedback making them appropriate for powering FPGA and SoC core rails. The A0R5 operates at 500 kHz, and the A1R0 at 1 MHz, to offer a choice of solution size versus efficiency.
