_______________Ge n e ra l De s c rip t io n

____________________________Fe a t u re s

The MAX1640 evaluation kit (EV kit) is an adjustable

switch-mode current source that operates from a 5.5V to

26V input. It is intended for microprocessor-controlled

battery chargers. The charging current, maximum volt-

age, and pulse-trickle charge are programmed with

external resistors. The EV kit is shipped configured for

a maximum charge voltage (6 cells). It is configured

as a step-down pulse-width modulator (PWM) with syn-

chronous rectification, allowing fast-charge currents up

to 1.5A with greater than 90% efficiency. The MAX1640

uses high-side current sense; this allows the load to

connect directly to ground, eliminating ground potential

errors. The MAX1641 uses low-side current sense.

♦ 5.5V to 26V Input Voltage Range

♦ Tight Current-Regulation Accuracy:

2% (MAX1641); 5% (MAX1640)

♦ Up to 1.5A Fast-Charge Current

♦ Up to 500kHz PWM Operation

♦ Pulse-Trickle Charge Current

♦ 100% Maximum Duty Cycle (low dropout)

♦ Synchronous Rectifier

♦ Surface-Mount Components

♦ Fully Assembled and Tested

The MAX1640 EV kit is a fully assembled and tested sur-

face-mount printed circuit board. It can also be used to

evaluate the MAX1641.
