XC9505Series  
ETR0705_006b  
2ch. Step-Down / Inverting DC/DC Controller IC  
☆GreenOperation-Compatible  
■GENERAL DESCRIPTION  
XC9505 series are PWM controlled, PWM/PFM switching 2 channel (step-down and inverting) DC/DC controller ICs. With 0.9V of  
internal standard voltage supply, and using externally connected components, the output 1 voltage (step-down DC/DC controller)  
can be set freely within a range of 0.9V to 6.0V. Since output 2 (inverting DC/DC controller) has a built-in 0.9V reference voltage  
(accuracy  
±2%), a negative voltage can be set with the external components.  
With a 180 kHz frequency, the size of the external components can be reduced. Switching frequencies of 300 kHz and 500 kHz are  
also available as custom designed products.  
The control of the XC9505 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 through to large output currents. Noise is easily reduced with PWM control since the frequency is fixed.  
The series gives freedom of control selection so that control suited to the application can be selected. Soft-start time is internally set  
to 10ms (output1) which offers protection against rush currents and voltage overshoot when the power is switched on.
