Brand: Monolithic Power Systems (MPS) · SKU: MPQ3367A · MPN: MPQ3367A · Category: Components
The MPQ3367A is a step-up converter with six channel current sources designed to drive white LED (WLED) arrays as backlighting for small- or medium-sized liquid crystal display (LCD) panels. It utilizes 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 LED brightness. The device regulates the current in each LED string to a value set by an external current-setting resistor, with 2.5% current matching between strings. Efficiency is improved by a low on-resistance MOSFET and low headroom voltage. It 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 supports analog, PWM, and mixed dimming modes with a PWM input, and includes a phase shift function for PWM dimming to reduce noise. Robust protections include OCP, OVP, OTP, and LED short/open protection. The
