GENERAL DESCRIPTION
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 is programmable in 100mV 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 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 0.5
μ
A.
With U.V.L.O. internal, the external transistor will be forcibly
switched off if used below the stipulated voltage.
