摘要：
A pulse width modulation apparatus and method operates a switch at one of four slew rates to minimize electromagnetic and harmonic interference or switching losses. One of the four slew rates is selected based on a detected over-current condition, with or without a start up operation condition, an over-temperature condition and a normal working mode.
