Specifications of MAX1577ZEVKIT

Function
Step Up, Step Down
Output Voltage
3.4 V, 4.6 V, 5.1 V
Output Current
1200 mA
The MAX1577Z evaluation kit (EV kit) is a fully assem-
bled and tested circuit for evaluating the MAX1577Z
white LED 1x/2x charge pump. The MAX1577Z EV kit
strobes a white LED at up to 1.1A using an on-board
pulse generator. In movie mode, it drives the LED at a
constant 220mA. The current levels are adjusted by
changing a resistor. The EV kit can also be used to
evaluate the MAX1577Y.
