HOW TO USE
Note:
When operating at VDD -1.8V and below (stepping-up from VIN=0.9V), it is necessary to pull-up to
VDD in order to allow the CE/PWM pin reach the VCEH voltage level. Please make sure that the
IC is in PWM control (SPWM=OFF) when operations start. If SPWM is ON, there are times when
chip enable might not operate.
* Please select your external components carefully (refer to the page 8).
By using external signals, the control of the XC9105 series can be switched between PWM control
and PWM/PFM automatic switching control. By inputting a voltage of more than VDD -0.2V to the
CE/PWM pin, PWM control can be selected. On the other hand, PWM/PFM automatic switching
control can be selected by inputting a voltage of less than VDD -1.0V.
Insert Rb and CB when using a
bipolar NPN Transistor.
When obtaining VDD from a source other than
VOUT, please insert a capacitor CIN between
the VDD pin and the GND pin in order to provide
stabler operations.
Please wire CL & CIN between the VOUT/VDD
pin and the GND pin. Strengthen the wiring
sufficiently.
With the XC9105, by connecting resistors of the same value (RM1, RM2) as shown in the diagram
to the left, it is possible to obtain chip disable with SCE ON and, SPWM ON or OFF, PWM/PFM
auto switching at Duty=25% with SCE OFF & SPWM ON, & PFM control with both switches OFF.
