Step-up, for LCD Bias Supply, 1-channel, PWM Control Switching Regulator Controller S-8333 Series

Description

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

Description

The S-8337/38 series is a CMOS step-up switching regulator (DC/DC Converter ICs) 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 (DC/DC Converter ICs) 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%).

Describe:

The S-8580/8581 Series is a step-down switching regulator developed using high withstand voltage CMOS process technologies.

This IC has high maximum operation voltage of 36 V and maintains high-accuracy FB pin voltage at ±1.5%. As suitable packages for high-density mounting, such as small-sized HSNT-6(2025), are adopted, this IC contributes to miniaturization of electronic equipment.

PWM control (S-8580 Series) or PWM / PFM switching control (S-8581 Series) can be selected as an option.

Since the S-8581 Series, which features PWM / PFM switching control, operates with PWM control under heavy load and automatically switches to PFM control under light load, it achieves high-efficiency operation in accordance with the device’s status.
