☆GO-Compatible ◆Input Voltage Range : 0.9~10.0V ◆Output Voltage Range : 1.5~6.5V(±2.5%) ◆Oscillator Frequency : 300kHz(±15%) ◆PWM/PFM Switching Control (XC6368) ◆High Efficiency : 84% (TYP.) ◆SOT-25 Package ■APPLICATIONS ■GENERAL DESCRIPTION ■FEATURES 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 capacitor. Output voltage is selectable in 100mV 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 reference 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 XC6367/68A, 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 externally. During stand-by (CE pin "Low"), supply current is reduced to less than 0.5μA.

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 oder 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 (TSS) is between MIN & MAX, as indicated in the graphs below, so please select soft-start capacitor value (CSS) to suit your application. 2. RFB1, CFB set up fzfb = 1 ÷ ( 2πx 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. 569 XC6367/6368 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (1) Output Voltage vs. Output Current 570 XC6367/6368 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (1) Output Voltage vs. Output Current (Continued) 571 XC6367/6368 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (2) Efficiency vs. Output Current 572 XC6367/6368 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (2) Efficiency vs. Output Current (Continued) 573 XC6367/6368 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (3) Ripple Voltage vs. Output Current 574 XC6367/6368 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (3) Ripple Voltage vs. Output Current (Continued) 575 XC6367/6368 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (4) Output Voltage vs. Ambient Temperature (5) Supply Current 1 vs. Ambient Temperature (6) Supply Current 2 vs. Ambient Temperature (7) Stand-by Current vs. Ambient Temperature (8) EXT "H" On Resistance vs. Ambient Temperature (9) EXT "L" On Resistance vs. Ambient Temperature 576 XC6367/6368 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (10) Oscillation Frequency vs. Ambient Temperature (11) Maximum Duty Ratio vs. Ambient Temperature (12) PFM Duty Ratio vs. Ambient Temperature (13) Efficiency vs. Ambient Temperature (14) Operation Start Voltage vs. Ambient Temperature (15) Operation Hold Voltage vs. Ambient Temperature 577 XC6367/6368 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (16) Oscillation Start Voltage vs. Ambient Temperature (17) Soft-Start Time vs. Ambient Temperature (18) CE "L" Voltage vs. Ambient Temperature (19) CE "H" Voltage vs. Ambient Temperature 578 XC6367/6368 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (20) Load Transient Response 579
