Current Mode PWMs

The SG3842 SG1843 SG2842 family of control IC's provides all the necessary features to implement off-line fixed frequency, current-mode switching power supplies with a minimum number of external components. Current-mode architecture demonstrates improved line regulation, improved load regulation, pulse- by-pulse current limiting and inherent protection of the power supply output Switch The bandgap reference is trimmed to 1% over temperature. Oscillator discharge current is trimmed to less than 10%. The SG3842 SG1843 SG2842 has under- voltage lockout, current limiting circuitry and start-up current of less than 1mA. The totem-pole output is optimized to drive the Gate of a power MOSFET The output is low in the off state to provide direct Interface to an N channel device. The SG3842 SG1843 SG2842 is specified for operation over the full military ambient temperature range of - 55C to 125C. The SG3842 SG1843 SG2842 is specified fo the industrial range of -25C to 85C, and th SG3842 SG3843 is designed for the commercial range of 0C to 70 By Microsemi Corporation
