Abstract :
A 500 V pre-regulator power IC is presented that is capable of supplying 20 V to 150 V into a variety of loads including televisions and DC motors. The chip measures 13.5 sq.mm., and uses a lateral IGBT (LIGBT) structure as a 10 A power switch. The control consists of novel current-mode sensing circuits that allow low-power, high-voltage sensing without using off-chip voltage dividers, The resulting circuit utilizes few components and demonstrates the feasibility for low EMI meeting FCC requirements
