Output Voltage Range

Output 1:

0.9V ~ 6.0V

! General Description

The XC9505 series are PWM control, PWM/PFM switching, 2

channel (step-down and inverting) DC/DC controller ICs.

With 0.9V of standard voltage supply internal, and using

externally connected components, the output 1 voltage (step-

down DC/DC controller) can be set freely within a range of 0.9V

~ 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.

(Step-Down DC/DC Controller)

Can be set freely with 0.9V(±

2.0%) of reference voltage

supply & external components

Output 2:

-30V ~ 0V

Can be set freely with 0.9V(±

2.0%) of reference voltage &

external components

(Inverting DC/DC Controller)

With a 180kHz frequency, the size of the external components

can be reduced. Switching frequencies of 300kHz and 500kHz

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.

Oscillation Frequency

180kHz ±15%

300kHz & 500kHz are available as custom

Output Current

Output 1 :more than 1000mA (VIN=5.0V,VOUT=3.3V)

Output 2 :more than - 100mA (VIN=5.0V,VOUT=- 7.5V)

Soft-Start Internally Set-Up (Output 1)

Stand-By Current

3.0µA (MAX)

Tr1,Tr2:XP162A12A6P, CL1, CL2=92uF(Tantalum),SD1:CMS02

The series gives freedom of control selection so that control

suited to the application can be selected.
