1 / 21 page 703 XC6365 6366 ETR0501_001.doc ◆ Input Voltage Range : 2.2~10.0V ◆ Output Voltage Range : 1.5~6.0V (±2.5%) ◆ Oscillator Frequency : 300kHz (±15%) ◆ Maximum Duty Ratio : 100% ◆ High Efficiency : 92% ◆ PWM/PFM Switching Control (XC6366) ◆ SOT-25 Package ■ GENERAL DESCRIPTION The XC6365/66 series are multi-functional step-down DC/DC converters with built-in high speed, low ON resistance drivers. An output current of more than 1A is possible using an externally connected transistor, coil, diode and capacitor. Output voltage is programmable in 100mV increments between 1.5V to 6.0V (VOUT) (±2.5% accuracy). Further, with 1.0V of standard voltage supply internal and using externally connected components, output voltage can be set up freely (FB). 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 XC6366 (PWM/PFM switchable) and the series is highly efficient from light loads to large output currents. In relation to soft-start time, both internally set-up 10msec types (A, B) and external resistor or capacitor regulated types (C, D) are available. During stand-by time (CE pin "Low" ), current consumption is reduced to less than 0.5μA. With U.V.L.O. internal, the external transistor will be forcibly switched off if used below the stipulated voltage. ■ APPLICATIONS ● Electronic information organizers ● Palmtops ● Cellular and portable phones ● Portable audio systems ● Various multi-function power supplies ■ TYPICAL APPLICATION CIRCUIT ■ FEATURES Input Voltage Range : 2.2V ~ 10V (VOUT type) Output Voltage Range : 1.5V ~ 6.0V programmable in 100mV increments (±2.5%) Oscillation Frequency : 300kHz (±15%) : Custom products for 180, 500kHz Output Current : More than 1.0A (VIN=5.0V, VOUT=3.0V) High Efficiency : 92% (TYP.)
