XC6367D

XC6367/XC6368 Series PWM Controlled,PWM/PFM Switchable Step-up DC/DC Controllers ETR0401_001 ☆GO-Compatible ■GENERAL DESCRIPTION The XC6367/68 series are multi-functional step-up DC/DC converter controllers with built-in high speed, low ON resistance drivers. High efficiency is 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 E 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. ■APPLICATIONS ●Electronic information organizers ●Palmtops ●Cellular and portable phones ●Portable audio systems ●Various multi-function power supplies ■FEATURES Input Voltage Range : 0.9V ~ 10V Operating Voltage Range : 2.0V ~ 10V Output voltage Range : 1.5V ~ 6.5V programmable in 100mV increments (±2.5%) Oscillation Frequency : 300kHz, 100kHz (±15%) Custom products for 180kHz, 500kHz Output Current High Efficiency Stand-by capability Selection : More than 200mA (VIN=1.8V, VOUT=3.3V) : 84% (TYP.) : ISTB=0.5μA (MAX.) : Soft-start set-up external Output voltage set-up internal (VOUT) Output voltage set-up external (FB) PWM/PFM Switching Control (XC6368) Package : SOT-25 ■TYPICAL APPLICATION CIRCUIT ■ TYPICAL PERFORMANCE CHARACTERISTICS 1/28 XC6367/XC6368 Series ■PIN CONFIGURATION （ ） ■PIN ASSIGNMENT PIN NUMBER XC6367/XC6368 A, B, C, D 5 2 4 3 E, F 5 4 1 EXT VDD GND CE : External Transistor Connection : Supply Voltage Input : Ground : Chip Enable (C, D, F Types: Soft Start External Set-Up, Soft Start Capacitor Connected) : Output Voltage Monitor (E, F Types: Output Voltage Monitor, Power Supply) (B, D Types: Output Voltage External Set-up) PIN NAME FUNCTION 1 2 VOUT (FB) ■PRODUCT CLASSIFICATION ●Selection Guide START Soft-Start Internally Set-Up Output Voltage Internally Set-Up (VOUT) VOUT=VDD pin XC6367A,XC6368A XC6367E,XC6368E XC6367B,XC6368B Output Voltage Externally Set-Up (FB) Soft-Start Externally Set-Up Output Voltage Internally Set-Up (VOUT) VOUT=VDD pin XC6367C,XC6368C XC6367F,XC6368F XC6367D,XC6368D Output Voltage Externally Set-Up (FB) 2/28 XC6367/XC6368 Series ■PRODUCT CLASSIFICATION (Continued) ●Ordering Information XC6367①②③④⑤⑥ XC6368①②③④⑤⑥ DESIGNATOR PWM Control PWM/PFM Switching Control DESCRIPTION SYMBOL A B ① Type of DC/DC Converter C D E F 15 ~ 65 ②③ Output Voltage 10 3 ④ Oscillation Frequency 1 2 5 ⑤ ⑥ Package Device Orientation M R L : FB type (B, D types): 10 fixed → ②=1, ③=0 fixed : 300kHz : 100kHz : 180kHz (Custom) : 500kHz (Custom) : SOT-25 (SOT-23-5) : Embossed tape, standard feed : Embossed tape, reverse feed DESCRIPTION : VOUT type: VOUT internally set-up, Soft-start internally set-up : FB type: VOUT externally set-up, Soft-start internally set-up : VOUT type: VOUT internally set-up, Soft-start externally set-up : FB type: VOUT externally set-up, Soft-start externally set-up : VOUT type: VOUT internally set-up, Soft-start internally set-up : VOUT type: VOUT internally set-up, Soft-start externally set-up : VOUT type: 3.0V output → ②=3, ③=0 3/28 XC6367/XC6368 Series ■BLOCK DIAGRAMS XC6367, XC6368 Series A, C, E, F types (VOUT) VOUT Error Amp. + - Phase Compensation PWM Comparator + Buffer, Driver VDD EXT CE Vref with Soft Start, CE PWM/PFM Controller Ramp Wave Generator, OSC GND * VOUT and VDD of the E and F types should be connected internally.

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 (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.
