The S-8333 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 1.08 MHz,
via the resistor connected to the ROSC pin.
The maximum duty ratio of PWM control can be controlled by the resistor connected to the RDuty pin. The soft-start
function at power application is accomplished by combining the reference voltage control and maximum duty control
methods. Even if the voltage of the FB pin is retained lower than the reference voltage due to the factor outside the IC, the
output voltage is raised by controlling the maximum duty. 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. The short-circuit protection function is cancelled when the power supply
is raised to the UVLO release voltage after it has been lowered to the UVLO detection voltage. 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.
