XC9502Series

ETR0702_001

2ch.Step-Up/Down DC/DC Controller ICs

☆GreenOperation-Compatible

■GENERAL DESCRIPTION

XC9502 series is PWM controlled, PWM/PFM automatic switching controlled, multi-functional, 2 channel step-up and down

DC/DC controller ICs. With 0.9V of standard voltage supply internal, and using externally connected components, the output

1 voltage (step-up DC/DC controller) can be set freely within a range of 1.5V to 30V. Since the output 2 (step-down DC/DC

controller) has a built-in 0.9V reference voltage (accuracy ±2%), 0.9V to 6.0V can be set using external components. 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 XC9502 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 10msec (Output1) and offers protection against

in-rush currents when the power is switched. This also prevents voltage overshoot.
