SUPER-SMALL PACKAGE CONTROL, PWM/PFM SWITCHING CONTROL STEP-UP SWITCHING REGULATOR
S-8355/56/57/58 Series
S-8355/56/57/58 Series CMOS step-up switching regulator which mainly consists reference voltage source, oscillation circuit, error amplifier, phase compensation circuit, control circuit (S-8355/57) PWM/PFM switching control circuit (S-8356/58). 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 from (from kHz, kHz, models), excellently designed error amplifier phase compensation circuit. S-8356/58 Series operation switched under light load control circuit with duty ratio PWM/PFM switching control circuit prevent decline efficiency operating current.
Features

Switching control types 1-1. 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. S-8355/57 Series, 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. 1-2. 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. This series particularly highly efficient DC-DC converter output current around conventional constant-duty DC-DC converters, pulses skipped when output load current low, causing fluctuation ripple frequency output voltage, resulting increase ripple voltage. S-8356/58 Series operates under control with pulse width duty changing from (78% types) high output load current area. other hand, S-8356/58 Series operates under control with pulse width duty fixed output load current area, pulses skipped when output load current according load current output switching transistor. oscillation circuit thus oscillates intermittently that resultant lower self-consumption prevent reduction efficiency load current. switching point from control control depends external devices (coil, diode, etc.), input voltage output voltage. Soft start function this built-in soft start circuit controls rush current overshoot output voltage when powering when ON/OFF switched level.
