Specifications of MAX16955EVKIT+

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The MAX16955 evaluation kit (EV kit) is a fully assem-
bled and tested PCB that contains all the components
necessary to evaluate the performance of the MAX16955
synchronous PWM step-down controller. The device is
available in a 16-pin TSSOP package and features an
exposed pad for enhanced thermal dissipation.
The EV kit requires a 6V to 36V power supply for normal
operation. The EV kit output is configured to 5V and can
deliver up to 5A output current. The EV kit can be easily
reconfigured to operate the controller in continuous PWM
mode, SKIP mode, or external synchronization operation.
The controller switching frequency is set to 400kHz. The
EV kit includes a jumper to enable the cir cuit and an LED
to monitor the power-good output.
