NCP1510
Advance Information
PWM Buck Converter with a
Very Low Iq During Low
Load Conditions
The NCP1510 is a tri鈭抦ode 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.
