STEP-UP, 1.2 MHz HIGH-FREQUENCY, PWM CONTROL SWITCHING REGULATOR CONTROLLER

The S-8337 S-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 V1.5%, and any voltage CAN be output by using an external output voltage setting resistor. By Seiko Instruments Inc.
