S-8337/8338 Series  
STEP-UP, 1.2 MHz HIGH-FREQUENCY, PWM CONTROL  
SWITCHING REGULATOR CONTROLLER

Rev.5.0_00  
The S-8337/8338 Series is a CMOS step-up switching regulator which mainly consists of a reference voltage  
circuit, an oscillator, an error amplifier, a PWM controller, an under voltage lockout circuit (UVLO), and a timer  
latch short-circuit protection circuit. Because its minimum operating voltage is as low as 1.8 V, this switching  
regulator is ideal for the power supply of an LCD or for portable systems that operate on a low voltage. The  
internal oscillation frequency can be set up to 1.133 MHz, via the resistor connected to the ROSC pin.  
With the S-8337 Series, the maximum duty ratio of PWM control can be controlled by the resistor connected to  
the RDuty pin. With the S-8338 Series, the maximum duty ratio is fixed (to 88%). The phase compensation  
and gain value can be adjusted according to the values of the resistor and capacitor connected to the CC pin.  
Therefore, the operation stability and transient response can be correctly set for each application. The  
reference voltage accuracy is as high as 1.0 V 1.5%, and any voltage can be output by using an external  
output voltage setting resistor.  
In addition, the delay time of the short-circuit protection circuit can be set by using the capacitor connected to  
the CSP pin. If the maximum duty condition continues because of short-circuiting, the capacitor externally  
connected to the CSP pin is charged, and oscillation stops after a specific time. This condition is cleared by  
re-application of power or by setting the switching regulator (S-8338 Series) to the shutdown status. A ceramic  
capacitor or a tantalum capacitor is used as the output capacitor, depending on the setting. This controller IC  
allows various settings and selections and employs a small package, making it very easy to use.
