Description

The XC9210 has an 0.9V (±2.0%) internal voltage, and using externally connected components, the output voltage can be set freely between 0.9V to 6.0V. With an internal switching frequency of 300kHz and 180kHz (custom) smaller, low cost external components can also be used.

The operation of the XC9210 series can be switched between PWM and PWM/PFM externally using the MODE pin. In PWM/PFM mode the XC9210 automatically switches from PWM to PFM during light loads and high efficiencies can be achieved over a wide range of load conditions. Output noise is reduced in PWM operation as the frequency is fixed.

The XC9210 is a synchronous PWM, PWM/PFM controller designed for low voltage step-down DC/DC converter applications. High efficiency is obtained through the use of a synchronous rectification topology. Efficiencies are maximised by using the low RDSon NChannel MOSFET switch which replaces the catch diode used in standard buck circuits. Soft-start time is internally set to 10msec offering protection against in-rush currents during start-up and preventing voltage overshoot.
