A Multitude of Solutions for Today’s Portable Electronics

High Efficiency DC-DC Converters

Key Features

? PWM buck converter operates either as an LDO or in PFM mode when output current decreases (NCP1500/01/19/ 1/ / / 9), maximizing efficiency at both light and full loads

? High switching frequencies allow use of smaller output filters, capacitors, and inductors,

while maintaining high efficiency
