Описание
EV3398E-U-00A is a 4-string, WLED controller with 80V return evaluation board. The MP3398E is a step-up controller with four current channels designed to drive WLED arrays for large-size LCD panel backlighting applications. The MP3398E is able to expand the number of LED channels with two or more ICs in parallel sharing a single power source. It employs peak current mode with a fixed switching frequency. The frequency is programmable through an external setting resistor. The MP3398E drives an external MOSFET to boost up the output voltage from a 4.5V to 33V input supply, and regulates the current in each LED string to the value set by an external current-setting resistor. The device applies four internal current sources for current balancing. The current matching achieves 2.3% regulation accuracy between strings. The low-regulation voltage on the LED current sources reduces power loss. The MP3398E supports direct PWM dimming and analogue dimming with PWM input.
