s General Description
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 (VOUT) is programmable in 0.1V steps from 1.5V to 6.5V (2.5% accuracy). Further, with 1.0V of standard voltage supply internal, and using externally connected components, output voltage (FB) can be set up at will. 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. Both internally set-up 10msec types (A, B, E), and adjustable soft-start time types (C, D, F) using externally connected resistors and capacitors are available. During stand-by time (CE pin "Low"), current consumption is reduced to less than 0.5A.

s Notes on Use
Take ample care to ensure that none of the IC's, nor the external component's, absolute maximum ratings are exceeded. Be extremely careful when selecting parts and do not limit your reference to the specifications and characteristics for the DC/DC converter alone. The IC also depends, to a great extent, upon the external components. Arrange the peripherals in the environs of the IC. In order to reduce wiring impedance, use short, thick wires. In particular, wire the load capacitor as close as possible and strengthen the ground wiring sufficiently. Ground current during switching may cause the IC's operations to become unstable due to changes in ground voltage, so please strengthen the IC's GND pin surroundings.
External Components
1. Soft start time set up
If you wish to lengthen soft start time we recommend that you use the C or D versions of the series which have soft start time externally set up. Soft start time (TSS) is between MIN & MAX, as indicated in the graphs below, so please select soft start condenser capacitance (CSS) to suit your application.
e
RFB1
CFB set up
(2 x CFB x RFB1 )
In order to achieve a value for fzfb within the range of 0.1kHz to 20kHz, we recommend that values for RFB1 & CFB are selected from the area indicated within the lines of fzfb = 0.1kHz and fzfb = 20 kHz as shown on the graph below. Please select combinations of values as close to the fzfb = 10kHz line as possible.
