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.
