Wide-Input, High-Frequency, Triple-Output Supplies

with Voltage Monitor and Power-On Reset

General Description

Features

The MAX8513/MAX8514 integrate a voltage-mode

PWM step-down DC-DC controller and two LDO con-

trollers, 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.

♦ 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 Applications

♦ Synchronizable to External Clock

♦ Adjustable Soft-Start

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 noise-

sensitive applications, the DC-DC controller can also be

synchronized to an external clock, minimizing noise inter-

ference. Operation above 1.1MHz reduces noise for high

data-rate xDSL applications. An adjustable soft-start and

adjustable foldback current limit provide reliable startup

and fault protection. The DC-DC controller output voltage

can be set externally to a voltage from 1.25V to 5.5V.

Current limiting is accomplished by inductor current sens-

ing for improved efficiency, or by an external sense resis-

tor for better accuracy.

♦ Lossless Adjustable Foldback Current Limit

♦ Power-On Reset with 140ms Delay

♦ Adjustable Input Power-Fail Warning for Dying

Gasp

♦ Selectable Output-Voltage Sequencing or

Output-Voltage Tracking

Ordering Information

The MAX8513/MAX8514s’ first LDO controller is

designed to provide a low-cost, high-current regulated

output from 0.8V to 5.5V using an N-channel MOSFET or

a low-current output using a low-cost NPN transistor. The

MAX8513’s second regulator can be used to generate

0.8V to 27V output with a low-cost PNP transistor. Both

LDO regulators can operate either from the DC-DC con-

troller output or from a higher voltage derived with a fly-

back overwinding on the DC-DC converter inductor. The

MAX8514’s second LDO regulator is designed to pro-

vide a negative output with an NPN transistor.

Functional Diagram

(4.5V TO 28V)

A sequence input allows the outputs to either power up

together, or for the DC-DC regulator to power up first

and each LDO controller to power up in sequence. An

input power-fail output (PFO) is provided for input

power-fail warning, such as in dying-gasp applications.

A power-on reset circuit with a 140ms delay is also

included to indicate when all outputs have achieved

regulation and stabilized.
