TOREX XC6367, XC6368 User Manual

XC6367/XC6368 Series
ETR0401_004a
PWM Controlled, PWM/PFM Switchable Step-up DC/DC Controllers
The XC6367/XC6368 series are multi-functional step-up DC/DC contro llers which provid e 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 recommend FB version, which has a 1.0V internal refere nce voltage. Using the FB version, the required output voltage can be set-up using 2 external resistors. With a 300kHz oscillation 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/ XC6368A, B, and E series is internally set to 10ms and XC6367/68C, D, and F series regulat e soft-start time by connecting resistors and capacitors externally. During stand-by (CE pin "Low"), supply current is reduced to less than 0.5μA.

NOTES ON USE
1. Take ample care to ensure that none of the IC's, nor the external component's, absolute maximum ratings are exceeded.
2. 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.
3. 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.
4. 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.Setting soft-start time In order to lengthen soft-start time we recommend that you use the C or D types of the series which have soft start time externally set-up. Soft-start time (T value (C

In order to achieve a value for fzfb within the range of 0.1kHz to 20kHz, we recommend that values for R 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.
