MAX1652- MAX1655
The MAX1652- MAX1655 are high-efficiency, pulsewidth-modulated (PWM), step-down DC-DC controllers in small QSOP packages. The MAX1653/MAX1655 also e in 16-pin narrow SO packages that are pinpatible upgrades to the popular MAX797. Improvements include higher duty-cycle operation for better dropout, lower quiescent supply currents for better light-load efficiency, and an output voltage down to 1V (MAX1655). The MAX1652- MAX1655 achieve up to...
