一,产品概述(General Description) 
The CXSU63153 series is a group of PFM controlled step-up DC/DC converter/controller ICs designed
to generate low supply voltage by the combination of PFM control and CMOS structure. The series is ideal for
applications where a longer battery life is needed such as in portable communication equipment. With a built-in
2.5ΩN-channel driver transistor, the CXSU63153A/C/E and CXSU63153A/C/E types provide a step-up operation
by using only a coil, a capacitor, and a diode connected externally.
The CXSU63153B, D and F versions can be used with an external transistor for applications requiring
larger currents.Output voltage is internally programmable in a range from 1.5V to 7.0V in increments of 100mV
(accuracy:±2.5%). Maximum oscillation frequency is set to 100kHz for CXSU63153 series. (At light loads,
it is set to 180kHz for the CXSU63153 series.) Options include products equipped with a CE pin (C and D
versions) that allows the IC to be shut down thereby reducing supply current and with separated VDD/VOUT
pins (E and F versions) to separate the power supply block and the output voltage detect block. With the
CXSU63153 series, maximum duty cycle is set to 75% (VDD=3.3V) making it suitable for use with large current
operations. The CXSU63153 series automatically switches duty ratio between 56% & 75% (VDD=3.3V) when it
senses changes in load to drop output ripple voltage and can support both large and small currents. The external
transistor types (B/D/F types) can be provided for applications, which require larger currents.
