S-8351

Super-Small Package PFM Control Step-Up Switching Regulator (DC/DC Converter ICs) S-8351/8352 Series

Description

The S-8351/8352 series is a CMOS PFM-control step-up switching regulator (DC/DC Converter ICs) that mainly consists of a reference voltage source, an oscillator, and a comparator. The PFM controller allows the duty ratio to be automatically switched according to the load (light load: 50%, high output current: 75%), enabling products with a low ripple over a wide range, high efficiency, and high output current (product types A, B, and D). Products with a fixed duty ratio of 75% are also available (product type C). With the S-8351 series, a step-up switching regulator (DC/DC Converter ICs) can be configured by using an external coil, capacitor, and diode. The built-in MOS FET is turned off by a protection circuit when the voltage at the CONT pin exceeds the limit to prevent it from being damaged. This feature, along with the mini package and low current consumption, makes the S-8351 series ideal for applications such as the power supply unit of portable equipment.

The S-8352 series, which features an external transistor, is suitable for applications requiring a high output current.

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 ¡À1.5%, 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

S-1740/S-1741

5.5 V Input, 100 mA Voltage Regulator with Supply Voltage Divided Output S-1740/1741 Series

Describe:

The S-1740/1741 Series, developed using CMOS technology, is a positive voltage regulator with the supply voltage divided output, which features super low current consumption and low dropout voltage.

The regulator block has low current consumption of 0.35 ¦ÌA typ. and high-accuracy output voltage of ¡À1.0%.

The function of the supply voltage divided output is prepared in the S-1740/1741 Series. The supply voltage divided output is a function that divides the input voltage (VIN) of the regulator into VIN/2 or VIN/3 and outputs the voltage. For example, this function makes it possible that the IC connects to a low voltage microcontroller A/D converter directly and the microcontroller monitors a battery voltage.
