paralleling multiple MOSFETs, characteristics common MOSFETs generally available market. Paralleling multiple power MOSFETs control higher currents, long MOSFET drivers adequately drive external FETs. Efficiency Higher efficiency will help with thermal issues, since wasted power converted into heat. Higher currents quickly generate more heat, airflow board space (and their cost) must considered. Switching Frequency Higher switching frequency provides lower ripple also lowers efficiency MOSFET transitions active region more often. issues also more complicated higher frequency. Accuracy Today's advanced processors need better accuracy support lower core voltages. There cost tradeoff when more accurate controller needed. Pre-biased Operation Voltages present outputs controller when turns prevent start-up and/or cause other complications. Controllers designed prebiased operation tolerate pre-biased condition safely start Protection Features Applications that many expensive processors peripheral single board benefit from long-term reliability ensured implementing controller's protection features.

Design Factors
Efficiency Solution Size charge pumps recommended when tradeoff between efficiency solution size needs made. Higher efficiency will directly translate into additional operating time battery-powered applications. Charge pumps achieve peak efficiencies typically require only capacitors operation. inductors, diodes FETs needed. Charge pumps come small packages such SOT-23 MSOP-8, which further reduce solution size. Output Current Charge pump converters allow small, power-efficient costeffective DC/DC solutions with output currents less than output voltage less than larger output currents, higher output voltages greater efficiency required, inductive switching converter more cost- space-efficient (pages 30-36).
Output Ripple Noise charge pumps reduce output voltage ripple minimum operating pair integrated charge pump loops with phase shift degrees. This helps avoid cost additional filtering output. Charge pumps also tend generate less noise than equivalent inductive switching converter equal output current rating. This important RFsensitive low-noise applications.
