APPLICATION NOTE 905
Adding POR Function to the MAX1864 Generating Two Outputs


Abstract:This application note shows how to add power-on reset (POR) to a power-supply controller, the MAX1864. The design
uses two positive regulator gain blocks to generate two outputs. Schematic and experimental waveforms are shown.

The MAX1864 power-supply controller is designed for cost-effective applications such as cable modem consumer premise
equipment (CPE), XDSL CPE and set-top boxes. It includes a current mode synchroniz
