Maxim Integrated Products (Sunnyvale, CA) debuted its new MAX1813 step-down controller. Intended for core CPU dc/dc converters in notebook computers, the controller features a five-bit DAC adjustable output. Maxim claims that the controller has ultra-fast transient response, high dc accuracy and high efficiency.

The MAX1813 features +/-1 percent Vout accuracy over line. It has an adjustable output slew rate and Quick-PWM architecture. The output range is adjustable between 0.6V and 2V, with a 2V to 8V battery input range. It features a 200/300/600/1,000kHz switching frequency and drives large synchronous-rectifier MOSFETs. Protection features include output under-voltage and over-voltage protection.

The MAX1813 is packaged in a 28-pin QSOP package. All units are screened for the extended temperature range spanning from -40 to 85 degrees C. Prices for the MAX1813 start at $4.76 in quantities of 1,000 and up.
