1 / 27 page 553 XC6367_6368 ETR0401_001.doc ◆ 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 ■ 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 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. ■ APPLICATIONS ● Electronic information organizers ● Palmtops ● Cellular and portable phones ● Portable audio systems ● Various multi-function power supplies ■ TYPICAL APPLICATION CIRCUIT ■ TYPICAL PERFORMANCE CHARACTERISTICS ■ 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 : More than 200mA (VIN=1.8V, VOUT=3.3V) High Efficiency : 84% (TYP.)
