About This Product

■Summary

The MP3214 is a low noise, high current charge pump designed to drive LEDs up to 500mA using a 2.7 to 5.5 volt input supply. High efficiency and low external component count (two small bypass capacitors, two small charge pump capacitors, and one programming resistor) make the MP3214 ideal for portable applications where small size and high efficiency are important. The MP3214 controls inrush current with a soft-start algorithm. The high frequency switching of the charge pump capacitor allows very small capacitance values. Output current is set by external resistor RSET. The brightness of the LED can be modulated by PWM on the enable pin. The MP3214 automatically adjusts the charge pump switching mode to optimize efficiency. The MP3214 is available in a 16-pin 3 x 3 QFN package.

■Features and benefits

・High efficiency ・Maximum output current of 500mA ・Wide power supply range from 2.7V to 5.5V ・Small solution size ・Soft start ・Low shutdown current ・LED open/short circuit protection ・No inductor ・Programmable output current ・PWM brightness control

■Available product numbers

・MP3214DQ-LF-P MP3214DQ-LF-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
