Test Conditions: Unless otherwise stated, CL: ceramic, recommended MOSFET should be connected.  
VOUT=3.3V, VIN=2.0V, IOUT=170mA  
NOTE:  
*1 Although the IC starts step-up operations from a VDD of 0.8V, the output voltage and oscillation frequency are stabilized at VDD>1.8V.  
Therefore, a VDD of more than 1.8V is recommended when VDD is supplied from VIN or other power sources.  
*2 With the XC9105 series, the CE pin also serves as a PWM/PFM switching pin. In operation, PWM control is selected when the voltage  
at the CE pin is more than VDD -0.2V. On the other hand, PWM/PFM automatic switching control at a duty = 25% is selected when  
the voltage at the CE pin is less than VDD -1.0V and more than VCEH.  
*3 The overcurrent limit circuit of this IC is designed to monitor the ripple voltage so please select your external components carefully to  
prevent VLMT being reached under low temperature conditions as well as normal operating conditions. Following current limiter  
circuit operations, which in turn causes the IC's operations to stop, the operations of the IC can be returned to normal with a toggle of  
the CE pin or by turning the power supply back on.
