说明

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 voltage, 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 synchronous 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.

The MAX1640 EV kit is a fully assembled and tested surface-mount printed circuit board. It can also be used to evaluate the MAX1641.
