MAX1644EVKIT

Evaluation Kit for the MAX1644


Please check latest availability status for a specific part variant.

Description

The MAX1644 evaluation kit (EV kit) provides a 1.5V output voltage from a +3V to +5.5V input source. It delivers up to 2A output current with 92% (max) efficiency. The MAX1644 is a step-down switching regulator with an internal synchronous rectifier to reduce the number of external components. It features a resistor-programmable fixed off-time as well as current-mode operation for superior load- and line-transient response.

The MAX1644 EV kit can also be used to evaluate other output voltages by changing the feedback resistors (R1 and R2) or by using the preset +3.3V or +2.5V settings.
