International Rectifier introduced the IRS2548D switched mode power supply control IC for high-power LED illumination including street lighting, stadium lighting and theatrical lighting. The chip, which combines power factor correction and half-bridge driver, offers greater than 88% efficiency for a 40 V/1,3 A HBLED load to deliver an efficient solution at power levels above 60 W. The device achieves PWM dimming down to less than 2% light output and offers protection features that include programmable PFC and half-bridge over-current protection, latch immunity and ESD protection. It also includes variable frequency oscillator, fixed internal 1,6 μs deadtime, internal bootstrap MOSFET, internal 15,6 V zener clamp diode on VCC and 250 μA startup.
