NCP1501, Dual Mode PWM/Linear Buck Converter
Pin # Symbol Pin Description 1 SHD Enable Pin for the NCP1501.
This pin is active high.
Internal pull down resistor forces the part off if the pin is not connected on the board.
2 SYN External Synchronization Signal Pin.
The device will operate in PWM mode if a clock signal is present.
Th
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.
