Wide-Input, High-Frequency, Triple-Output Supplies with
Voltage Monitor and Power-On Reset
General Description
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 allow for the optimization of cost, size, and efficiency.
For noisesensitive applications, the DC-DC controller can also be synchronized to an external clock,...
