- Part of the XC6367 comparator family.
- Part of the XC6367 comparator family.
XC6367/XC6368 Series
ETR04001-006a
PWM Controlled, PWM/PFM Switchable Step-up DC/DC Controllers
☆Green Operation patible
- GENERAL DESCRIPTION
The XC6367/XC6368 series are multi-functional step-up DC/DC controllers which provide high efficiency outputs by using an externally connected transistor, coil, diode and capacitor.
Output voltage is selectable in 0.1V increments within a range of 1.5V ~ 6.5V (±2.5%). For output voltages outside this range, we remend FB version, which has a 1.0V internal reference voltage. Using the FB version, the required output voltage can be set-up using 2 external resistors.
With a 300k Hz oscillation frequency, the size of the external ponents 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/ XC6368A, B, and E series is internally set to 10ms and XC6367/68C, D, and F series regulate soft-start time by connecting resistors and capacitors externally.
During stand-by (CE pin "L"), supply current is reduced to less than 0.5μA.
