NCP1512
Advance Information PWM Buck Converter with a Very Low Iq During Low Load Conditions
The NCP1512 is a tri-mode
regulator that operates either as a Synchronized PWM Buck Converter, PWM Buck Converter with internal oscillator or as a Pulsed Switching
Regulator.
If a synchronization signal is present, the NCP1512 operates as a current mode PWM converter with synchronous rectification.
The optional external frequency input signal allows the user to control the location of the spurious frequency noise generated by a PWM converter.
The Pulsed Switching
Regulator mode is active when the Sync Pin is Low.
The Pulsed Mode is an extremely low quiescent current Buck Converter.
