SFA0001
3D CAD DataSFA0001 is a flyback type switching power supply IC with built-in high precision error amplifier. Few external components are required for control, contributing to reduction in design time. Suited for creating a compact, standardized product.
Design Support
Features
-
・Mountable on small surface, full molding 8PIN package (SOP8)
・High-precision error amps incorporated in ICs and switching power supply can be simply configured. (All temperature±2%)
・IC power pin voltage 36V resistance
・Controlled by fixed frequency PWM method and oscillation frequency can be set by external capacitor
・Current mode control
・Vehicle mountable product
・Soft start function which can set time by external capacitor is included
・Overcurrent protection function (OCP)→Turns OFF the MOSFET in pulse-by-pulse
・Overload protection function (OLP) → Auto-restart
・Overheat thermal protection→Restart by sensed temperature hysteresis
