Specifications of MAX8727EVKIT

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The MAX8727 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board that contains a
pulse-width-modulated (PWM) step-up DC-DC convert-
er. The EV kit is configured to operate with a 1.2MHz
switching frequency. It operates from a 2.6V to 5.5V DC
supply voltage, is configured for a 15V output, and can
provide 600mA with a 4.5V input.
The MAX8727 EV kit features low quiescent current and
high conversion efficiency (90%). The high switching
frequency allows for the use of small surface-mount
components.
