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
