PMIC Provides Up To 93% Efficiency

The MAX8930 power-management IC (PMIC) for cell phone displays integrates a white LED driver, passive-matrix organic LED driver, and a linear drop-out regulator in a 10-mm2 package. It employs an adaptive-charge-pump architecture (1x or -0.5x) and advanced dimming techniques to achieve up to 93% efficiency. Moreover, it averages 90% efficiency over the 3.5V to 3.7V input range in which the lithium-ion cell operates most often. Other features include an I2C-compatible control interface. Prices start at $3.45 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
