Step-Down Converter Accelerates Application Processors

Allowing app processors to run at maximum clock speed, the MAX8952 synchronous, dc/dc step-down converter delivers up to 2.5A of output current from a 4 mm² wafer-level package. The device operates from an input supply as low as 2.5V and employs an I²C interface that enables dynamic voltage scaling and programming of the output voltage between 770 mV and 1.4V in 10-mV steps. Operating in fixed-frequency PWM or in power-save mode, it can also be synched to an external clock. Prices start at $1.76 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
