General Description
The XC9501 series are PWM controlled, PWM/PFM automatic
switching controlled, multi-functional, dual step-up DC/DC
converter controller ICs.
With 0.9V (
±
2%) of standard voltage supply internal, and using
externally connected components, output voltage can be set
freely on both DC/DC controllers between 1.5V to 30V.
With a 180kHz frequency, the size of the external components
can be reduced. 300kHz and 500kHz switching frequencies
are also available as custom-designed products.
The control of the XC9501 series can be switched between
PWM control and PWM/PFM automatic switching control using
external signals. Control switches from PWM to PFM during
light loads when automatic switching is selected and the series
is highly efficient from light loads to large output currents.
Noise is easily reduced with PWM control since the switching
frequency is fixed.
The XC9501 series provides the option of being able to select
the control suited to the application.

XC9501 Series
2ch. Step-up DC/DC Controller ICs.
Soft-start time is internally set to 10msec which offers
protection against rush currents when the power is switched on
and also against voltage overshoot.
