STEP-UP, PWM CONTROL or PWM / PFM SWITCHABLE BUILT-IN TRANSISTOR SWITCHING REGULATOR
S-8353/8354 Series
The S-8353/8354 Series is a
CMOS step-up switching regulator which mainly consists of a reference
voltage source, an oscillation circuit, a power MOS FET, an error amplifier, a phase compensation circuit, a PWM control circuit (S-8353 Series) and a PWM / PFM switching control circuit (S-8354 Series).
The S-8353/8354 Series can configure the step-up switching regulator with an external coil, capacitor, and diode.
In addition to the above features, the small package and low current consumption make the S-8353/8354 Series ideal for portable equipment applica...
