XC6366B103MR-G

The XC6365/XC6366 series are multi-functional step-down DC/DC controllers which have 1A output current capability by using an externally connected transistor, coil, diode and capacitor. Output voltage is programmable in 0.1V increments 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. Soft start time of XC6365/ XC6366A, B series is internally set to 10ms and XC6365/66C, D series regulate soft-start time by connecting resistors and capacitors externally. During stand-by time (CE pin "Low" ), current consumption is reduced to less than 0.5 μA.
