The MAX8513/MAX8514 integrate a voltage-mode PWM step-down DC-DC controller and two LDO controllers, a voltage monitor, and a power-on reset for the lowest-cost power-supply and monitoring solution for xDSL modems, routers, gateways, and set-top boxes. The DC-DC controller switching frequency can be set with an external resistor from 300kHz to 1.4MHz, to all.
