It switches at 180 kHz and operates from a 3.3 V to 16 V input rail. The part comes in an 8-pin DIP through-hole package and is rated for the commercial temperature range of 0 °C to 70 °C. This is a straightforward, no-frills regulator for board-level point-of-load conversion where you need a single positive rail and can live without synchronous rectification. ## Package and mounting The 500 mA current rating is the continuous output this part can sustain. ## RoHS non-compliant — plan accordingly The MAX748ACPA is marked RoHS non-compliant. If your BOM requires lead-free assembly or your customer mandates RoHS, this part cannot be used. That is a hard gate for many designs. ## Sourcing and supply position For BOM lines that can accept a non-RoHS component, it is available through independent distribution and quoted to order against an RFQ.","metaTitle":"MAX748ACPA Step-Down Buck Converter, 500 mA, 180 kHz, 8-DIP","metaDescription":"MAX748ACPA PWM step-down DC-DC controller, 500 mA output, 3.3 V fixed, 180 kHz, 8-DIP through-hole.
