XC9206/XC9207/XC9208Series  
ETR0503_002  
PWM, PWM / PFM Switchable Step-Down  
DC / DC Converters With Driver Transistor Built-In  
☆GO-Compatible  
■GENERAL DESCRIPTION  
The XC9206/XC9207/XC9208 series is a group of DC/DC converters with a built-in 0.4Ω P-channel driver transistor, offered  
in a SOT-25 package. The ICs are designed to provide high efficiencies and a stable power supply with an output current of  
500mA using only a coil, a diode and two ceramic capacitors connected externally.  
Minimum operating voltage of the XC9206/9207 is 1.8V and 2.0V for XC9208. Output voltage is internally programmable in  
a range from 0.9V to 4.0V in 100mV increments (accuracy: ±2.0%). Oscillation frequency is selectable from 300kHz, 600kHz  
and 1.2MHz so that the frequency best suited to your particular application can be selected. Each series features different  
operation modes: PWM control (XC9206 series), automatic PWM/PFM switching control (XC9207 series) and manual  
PWM/PFM switching control (XC9208 series). The series gives fast transient response, low ripple and high efficiency over  
the full range of load (from light load to high output current conditions). The soft start and current control functions are  
internally optimized. During stand-by, all circuits are shutdown to reduce current consumption to as low as 1.0μA or less.  
With the built-in U.V.L.O. (Under Voltage Lock Out) function, the internal P-channel driver transistor is forced OFF when input  
voltage becomes 1.4V or lower.
