NCP1406, NCV1406
25 V/25 mA PFM Step-Up
DC-DC Converter
The NCP1406 is a monolithic stepup DCDC converter operating
in a Pulse Frequency Modulation (PFM) scheme with constant peak
current control. It integrates a 0.8 A, 0.7 W internal power switch and
sensing resistor to monitor inductor current. This control scheme
maintains high efficiencies over the entire load current range. The
wide input voltage range, from 1.4V to 5.5 V, enables the user to
operate the device from a LiIon battery or a twocell Alkaline
NiMH. Its ability to boost voltages up to 25 V, and to provide 1 W
output power, makes the NCP1406 the perfect solution for biasing
small and large OLED panels. This device also makes a perfect
solution for biasing a great number of white LEDs in series. A Chip
Enable pin allows the user to control the device to extend the battery
life during standby, and can be pulsewidth modulated for white
LED applications. The versatility of the NCP1406 allows it to be
configured not only as a stepup converter, but also as an inverter and
as a stepdown converter. This solution is proposed in a
spacesaving TSOP5 package.
