EV3318-C-00A 3-Channel, Step-Up White LED Driver with I2C Interface Evaluation Board
The EV3318-C-00A is an evaluation board for the MP3318, a white LED step-up driver with a 2.7V to 5.5V input voltage range and 3-channel current sinks. The MP3318 uses peak current control mode to regulate the LED current set by an internal register.
The MP3318 integrates a 250mΩ, 42V MOSFET with a 38V maximum LED voltage output. The IC has the ability to drive LEDs in series for >5” liquid crystal display (LCD) panel applications.
The MP3318 features linear and exponential analog dimming with 11-bit, ultra-high resolution that regulates the dimming current. The IC’s automatic switching frequency function optimizes efficiency.
In addition, the MP3318 offers LED open protection, LED short protection, cycle-by-cycle current limit protection, over-voltage protection (OVP), and thermal shutdown. The I2C interface can set the internal register to program the MP3318 for flexible applications, such as dimming mode, LED current ramp, and featured protection functions.
The MP3318 is available in an ultra-small WLCSP-12 (1.3mmx1.7mm) package.
