XC6366

The XC6365/66 series are multi-functional step-down DC/DC converters with built-in high speed, low ON resistance drivers. An output current of more than 1A is possible using an externally connected transistor, coil, diode and capacitor.

Output voltage of XC6365/66  is programmable in 0.1V steps between 1.5V to 6.0V (VOUT) (±2.5% accuracy). Further, with 1.0V of standard voltage supply internal and using externally connected components, output voltage can be set up freely (FB).With a 300kHz switching frequency, the size of the external components can be reduced. Control switches from PWM to PFM during light loads with the XC6366 (PWM/PFM switchable) and the series is highly efficient from light loads to large output currents. In relation to soft-start time, both internally set-up 10msec types (A,B) and external resistor or capacitor regulated types (C,D) are available. During stand-by time (CE pin "Low" ), current consumption is reduced to less than 0.5A.With U.V.L.O internal, the external Tr. will be forcibly switched off if used below the stipulated voltage.
