XC9503 - 2ch Step-down DC/DC Controller

General Description

XC9503 series are PWM controlled, PWM/PFM automatic switching controlled, multi-functional, 2 channel step-down DC/DC controller ICs.

Since the series has a built-in 0.9V reference voltage (accuracy 2%), 0.9V to 6.0V can be set using external components.

XC9503 Series 2ch.Step-Down DC/DC Controller ICs ETR0703_003 GreenOperation Compatible GENERAL DESCRIPTION XC9503 series are PWM controlled, PWM/PFM automatic switching controlled, multi-functional, 2 channel step-down DC/DC controller ICs. Since the series has a built-in 0.9V reference voltage (accuracy 2%), 0.9V to 6.0V can be set using external components. With a 300kHz frequency, the size of the external components can be reduced. Switching frequencies of 180kHz & 500kHz are also available as custom-designed products. The control of the XC9503 series can be switched between PWM control and PWM/PFM automatic switching control using external signals.
