NCP1511
Up to 500 mA, High
Efficiency Synchronous
StepDown DCDC Converter
in Chip Scale Package
The NCP1511 stepdown PWM DCDC converter is optimized
for portable applications powered from 1cell Liion or 3cell
Alkaline/NiCd/NiMH batteries. This DCDC converter utilizes a
currentmode control architecture for easy compensation and better
line regulation. It also uses synchronous rectification to increase
efficiency and reduce external part count. The NCP1511 optimizes
efficiency in light load conditions when switched from a normal
PWM mode to a “pulsed switching” mode. The device also has a
builtin oscillator for the PWM circuitry, or it can be synchronized to
an external 500 kHz to 1000 kHz clock signal. Finally, it includes an
integrated softstart, cyclebycycle current limiting, and thermal
shutdown protection. The NCP1511 is available in a chip scale
package.
