description (continued)
Three operating modes can be programmed using the SNOOZE pin. When SNOOZE is low, the device is put
into snooze mode. In snooze mode, the device operates with a typical quiescent current of 2
A while the output
voltage is maintained at 3.3 V
±6%. This is lower than the self-discharge current of most batteries. Load current
in snooze mode is limited to 2 mA. When SNOOZE is high, the device is put into normal operating mode. During
normal operating mode, the device operates in the newly developed linskip mode where it switches seamlessly
from the power saving pulse-skip mode at light loads to the low-noise constant-frequency linear-regulation
mode once the output current exceeds the linskip current threshold of about 7 mA. In this mode, the device
operates from the internal oscillator. The device is synchronized to an external clock signal if SNOOZE is
clocked; thus switching harmonics can be controlled and minimized.
Only four external capacitors are needed to build a complete low-ripple dc/dc converter. The push-pull operating
mode of two single-ended charge pumps assures the low output voltage ripple as charge is continuously
transferred to the output. All the devices can start with full load current. The devices include a low-battery
detector that issues a warning if the battery voltage drops below a user-defined threshold voltage or a
power-good detector that goes active when the output voltage reaches about 90% of its nominal value. This
dc/dc converter requires no inductors; therefore, EMI of the system is reduced to a minimum, making it easier
to use in designs. It is available in the small 10-pin MSOP package (DGS).
