■GENERAL
DESCRIPTION
The XC6365/XC6366 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 is programmable in 0.1V increments between 1.5V to 6.0V (V
OUT
) (±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 10ms 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 UVLO internal, the external transistor will be forcibly switched off if used below the stipulated voltage.
