MAX8513 - Triple-Output Supplies

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.

Key Features

  • Low-Cost DC-DC Controller with Two LDOs.
  • Wide Input Range: 4.5V to 28V.
  • 300kHz to 1.4MHz Adjustable Switching Frequency.
  • Low Noise for High Data-Rate xDSL.

19-3178; Rev 0; 2/04 KIT ATION EVALU E L B A AVAIL www.DataSheet4U.com 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, minimizing noise interference. Operation above 1.
