Advance Information

PWM Buck Converter with a

Very Low Iq During Low

Load Conditions

The NCP1510 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 NCP1510 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. NCP1510 operates in a PWM mode with an internal

oscillator when the Sync Pin is held high. The NCP1510

configuration allows the flexibility of efficient high power operation

and low input current during system sleep modes.
