Evaluation Tools

The EV3393-F-00A is an evaluation board for the MP3393, a step-up controller with 8-channel external-transistor current sources.
The MP3393 uses current mode, fixed frequency architecture. It drives an external MOSFET to boost up the output voltage from 9V to 32V input supply. The switching frequency is programmable by an external setting resistor.
The MP3393 integrates the constant current control circuit to regulate the current in each LED string to the value set by an external current feedback resistor. And the current matching can achieve 1.2% regulation accuracy between strings. Its low 202mV regulation voltage on LED current sources reduces power loss and improves efficiency.
The EV3393-F-00A is a fully assembled and tested PCB. It generates a 1.6A (200mA/string, 8 strings) output current at LED load from a 12V to 30V input range. Switching frequency is set at 160kHz.
