SPF8201 DATA SHEET
Ver.1
1. General Description
SPF8201 is an IC for flyback type switching power control equipped with high voltage power MOSFET.
It has a smaller number of external parts necessary for control, and making it easier to design circuits, and suitable for
downsizing and standardization of power.
2. Features
●For automotive, AEC-Q100 Grade1 Qualified
●800V rating, built-in high voltage power MOSFET
●Built-in startup circuit (standby power consumption and external components can be reduced)
●High-precision error amp (total temperature±2%) incorporated in ICs and switching power supply can be simply
configured
●Controlled by fixed frequency PWM method and oscillation frequency can be set by capacitance of external capacitor.
●Current mode control
●Built-in leading edge blanking function
●Soft start function which can set time by capacitance of external capacitor is included.
●Compact surface mount TSFP40 pin package (HSOP40 package)
●Various protection functions
・Overcurrent protection function (OCP)→Turns OFF the power MOSFET
in pulse-by-pulse.
・Overload protection function (OLP) → Auto-restart
・Overheat thermal protection→Auto-restart by sensed temperature hysteresis
・Burst function under light load condition
3. Standard connection
Q1
Since the switching noise
caused by Q1 may affect the
operation of an IC, appropriate
design for peripheral circuits is
required to prevent the
malfunction of an IC by adding
snubber circuit and /or filter
circuit.
