NCP1501
Dual Mode PWM/Linear
Buck Converter
The NCP1501 is a dual mode regulator that operates either as a
PWM Buck Converter or as a Low Drop Out Linear Regulator. If a
synchronization signal is present, the NCP1501 operates as a current
mode PWM converter with synchronous rectification. The
synchronization signal allows the user to control the location of the
spurious frequency noise generated by a PWM converter. Linear mode
is active when a synchronization signal is not present. The NCP1501
configuration allows an efficient high power operation and low noise
during system sleep modes.
