NCP1512 Datasheet Pwm Buck Converter

Manufacturer: onsemi

Overview: 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. NCP1512 operates in a PWM mode with an internal oscillator when the Sync Pin is held high. The NCP1512 configuration allows the flexibility of efficient high power operation and low input current during system sleep modes.
