SUPER-SMALL PACKAGE PWM CONTROL, PWM/PFM

CONTROL STEP-UP SWITCHING REGULATOR

The S-8353/8354 series is a CMOS step-up switching regu-

lator which consists of a reference voltage source, an oscil-

lation circuit, a power MOS FET, an error amplifier, a phase

compensation circuit, a PWM controller (S-8353) and a

PWM/PFM switching controller (S-8354).

The step-up switching regulator can be configured simply by

attaching a coil, capacitor, and diode externally. In addition

to the above features, the small package and low power

consumption of this series make it ideal for portable device

applications requiring high efficiency. The S-8353 series re-

alizes low ripple, high efficiency, and excellent transient char-

acteristics due to its PWM controller, which can vary the duty

ratio linearly from 0% to 83% (from 0% to 78% for 250 kHz

models), optimally-designed error amplifier, and phase com-

pensation circuits.

The S-8354 series features a PWM/PFM switching controller

that can switch the operation to a PFM controller under a

light load to prevent a decrease in efficiency.
