NSOT-25 Package

The XC6367/68 series are multi-functional step-up DC/DC converter

controllers with built-in high speed, low ON resistance drivers.

Large output currents are possible using an externally connected

transistor, coil, diode and condenser.

Output voltage is selectable in 0.1 steps within a 1.5V ~ 6.5V range

(±2.5%). For output voltages outside this range, we recommend this FB

version, which has a 1.0V internal reference voltage. Using this version,

the required output voltage can be set-up using 2 external resistors.

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 XC6368

(PWM/PFM switchable) and the series is highly efficient from light loads

to large output currents.

Soft start time of XC6367/68A, B, and C series is internally set to

10msec and XC6367/68C, D, and F series regulate soft start time by

connecting resistors and capacitors exteranally.

During stand-by time (CE pin "Low"), current consumption is reduced to

less than 0.5µA.
