2-step voltage regulation improves performance and decreases CPU temperature in portable computers
John Seago
Abstract
2-step regulation allows CPU power supply optimization in portable applications. OPTI-LOOP compensation and a 3.5V to 36V input range make the LTC1736 a good choice for either 1-step or 2-step configurations.

2-step regulation allows CPU power supply optimization in portable applications. Higher CPU clock frequencies mean lower core voltages, higher supply currents and more CPU power dissipation. Regulating CPU power from 5V reduces regulator switching losses permitting a higher switching frequency. Higher frequency operation results in smaller inductor size, fewer ...
