PWM Step-Down DC/DC Controller
This part is not recommended for new designs, please use XC9220
The XC6365 series are multi-functional step-down DC/DC controllers 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 is programmable in 100mV 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.
The XC6365 uses fixed frequency PWM mode and deliveres maximum efficiencies at larger 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 0.5μA. With U.V.L.O internal, the external Tr. will be forcibly switched off if used below the stipulated voltage.
