S-8355/56/57/58 Series
S-8355/56/57/58 Series CMOS step-up switching regulator controller which mainly consists reference voltage source, oscillation circuit, error amplifier, phase compensation circuit, control circuit (S-8355/57 Series) PWM/PFM switching control circuit (S-8356/58 Series). With external low-ON-resistance Power MOS, this product ideal applications requiring high efficiency high output current. S-8355/57 Series realizes ripple, high efficiency, excellent transient characteristics control circuit whose duty ratio varied linearly from (from kHz, kHz, models), excellently designed error amplifier phase compensation circuits. S-8356/58 Series features PWM/PFM switching controller that switch operation controller with duty ratio under light load prevent decline efficiency operating current.

Switching Control Types Control (S-8355/57 Series)
S-8355/57 Series DC-DC converter using pulse width modulation method (PWM) features current consumption. conventional DC-DC converters, pulses skipped when output load current low, causing fluctuation ripple frequency output voltage, resulting increase ripple voltage. switching frequency does change, although pulse width changes from (78% types) corresponding each load current. ripple voltage generated from switching thus removed easily through filter because switching frequency constant.
PWM/PFM Switching Control (S-8356/58 Series)
S-8356/58 Series DC-DC converter that automatically switches between pulse width modulation method (PWM) pulse frequency modulation method (PFM), depending load current, features current consumption. S-8356/58 Series operates under control with pulse width duty changing from (78% types) high output load current area. S-8356/58 Series operates under control with pulse width duty fixed 15%, pulses skipped according load current. oscillation circuit thus oscillates intermittently that resultant lower self current consumption prevents reduction efficiency load current. switching point from control control depends external devices (coil, diode, etc.), input voltage output voltage. This series especially highly efficient DC-DC converter output current around
