NCP1523
3 MHz, 600 mA,
HighEfficiency, Adjustable
Output Voltage Stepdown
Converter
The NCP1523 step
down PWM DC
DC converter is optimized for
portable applications powered from 1
cell Li
ion or 3 cell
Alkaline/NiCd/NiMH batteries. The device is available in an
adjustable output voltage from 0.9 V to 3.3 V. It uses synchronous
rectification to increase efficiency and reduce external part count. The
device also has a built
in 3 MHz (nominal) oscillator which reduces
component size by allowing use of a small inductor and capacitors.
NCP1523 is available in automatic switching PWM/PFM
(NCP1523FCT2G) improving system efficiency and in PWM mode
only (NCP1523BFCT2G) offering a very efficient load transient
solution.
Additional features include integrated soft
start, cycle
by
cycle
current limiting and thermal shutdown protection. The NCP1523 is
available in a space saving, 8 pin chip scale package.
Features
Sources up to 600 mA
3 MHz Switching Frequency
Up to 93% Efficiency
Synchronous rectification for higher efficiency
Thermal limit protection
Shutdown current consumption of 0.3 A
These are Pb
