EVQ3367A-R-00A Evaluation Kit 6-Channel, Maximum 150mA/Ch, Boost WLED Driver with 15000:1 Dimming Ratio and I2C Interface Evaluation Board, AEC-Q100 Qualified
The EVQ3367A-R-00A is an evaluation board designed to demonstrate the capabilities of the MPQ3367A, a step-up converter with six channel current sources. It is designed to drive white LED (WLED) arrays as backlighting for small- and medium-sized LCD panels.
The device uses peak current mode as its pulse-width modulation (PWM) control architecture to regulate the boost converter. Six channel current sources are applied to the LED cathode to adjust the LED brightness. The MPQ3367A regulates the current in each LED string to the value set by an external current-setting resistor, with 2.5% current regulation accuracy between strings.
A low on resistance MOSFET and low headroom voltage improve efficiency. For ease of use, the MPQ3367A features a standard I2C digital interface. The switching frequency (fSW) can be configured via a resistor, the I2C interface, or an external clock. The MPQ3367A features analog dimming, PWM dimming, and mixed dimming modes with a PWM input. The dimming mode can be selected via the I2C interface or the MIX/AD pin. The device also has a phase shift function to eliminate noise during PWM dimming.
Full protection features include over-current protection (OCP), over-voltage protection (OVP), over-temperature protection (OTP), and LED short/open protection. The LED current also decreases at high temperatures automatically. The MPQ3367A is available in a QFN-24 (4mmx4mm) package.
Communication Interface Device USB to I2C/PMBus, included with product evaluation kit or can be purchased separately.
