MAX1544/MAX1545 Evaluation Kits

________________________________________________________General Description

_________________________________________________________________________________________Features

Quad-Phase Quick-PWM^TMEV Kit

The MAX1544/MAX1545 evaluation kits (EV kits)

demonstrate the high-power, dynamically adjustable

multiphase notebook CPU application circuit. This DC-DC

converter steps down high-voltage batteries and/or AC

adapters, generating a precision, low-voltage CPU core

VCC rail. The MAX1544 EV kit meets the mobile and

desktop AMD Hammer CPU transient voltage

specification. The MAX1545 EV kit meets the desktop and

Mobile and Desktop P4 or AMD Hammer

Compatible

Active Voltage Positioning with Adjustable Gain,

Offset and Remote Sensing

High Speed, Accuracy and Efficiency

Low Bulk Output Capacitor Count

mobile Pentium

(P4) CPUs transient voltage

specification. The MAX1544/MAX1545 kits consist of the

MAX1544 or MAX1545 Dual-Phase Quick-PWM™ step-

down controller, two MAX1980 slave controllers and the

MAX6590 temperature sensor. The MAX1544/MAX1545

kits include active voltage positioning with adjustable gain

and offset, reducing power dissipation and bulk output

capacitance requirements. The kit features independent

four-level logic inputs for setting the suspend voltage

(S0/S1).

Multiphase Fast-Response Quick-PWM

Architecture

MAX1544/MAX1545 Dual-Phase Controller

Two MAX1980 Slave Controllers

7V to 24V Input Voltage Range

5-Bit On-Board DAC

Mobile P4: 0.60V to 1.75V Output Range

Desktop P4: 1.10V to 1.85V Output Range

AMD Hammer: 0.675V to 1.55V Output Range

68A Load-Current Capability (17A Each Phase)

300kHz Switching Frequency

The MAX1980 provides additional gate drive circuitry,

phase synchronization, current limit, and current

balancing. Precision slew-rate control provides “just-in

time” arrival at the new DAC setting, minimizing surge

currents to and from the battery.

This fully assembled and tested circuit board provides a 5-

bit digitally adjustable output voltage from a 7V to 24V

battery input range. The EV kit operates at 300kHz

switching frequency and has superior line- and load-

transient response.
