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 applications requiring high efficiency.
The S-8353 Series realizes low ripple, high efficiency, and excellent transient characteristics due to its PWM control circuit
whose duty ratio can be varied linearly from 0% to 83% (from 0% to 78% for 250 kHz models), an excellently designed error
amplifier, and phase compensation circuits.
The S-8354 Series features a PWM / PFM switching controller that can switch the operation to a PFM controller with a duty
ratio is 15% under a light load to prevent a decline in the efficiency due to the IC operating current.
Features
Low voltage operation: Startup at 0.9 V min. (IOUT = 1 mA) guaranteed
Low current consumption : During operation 18.7
μA (3.3 V, 50 kHz, typ.)
During shutdown: 0.5
μA (max.)
Duty ratio : Built-in PWM / PFM switching control circuit (S-8354 Series)
15 % to 83 % (30 kHz and 50 kHz models)
15 % to 78 % (250 kHz models)
External parts : Coil, capacitor, and diode
Output voltage : Selectable in 0.1 V steps between 1.5 V and 6.5 V (for VDD / VOUT separate types)
Selectable in 0.1 V steps between 2.0 V and 6.5 V (for other than VDD / VOUT separate types)
Output voltage accuracy :
±2.4%
Oscillation frequency : 30 kHz, 50 kHz, and 250 kHz selectable
Soft start function : 6 ms (50 kHz, typ.)
Lead-free, Sn 100%, halogen-free
