TOP100 概述

  The TOP100 implements, with only three pins, all functions necessary for an off-line switched mode control system: high voltage N-channel power MOSFET with controlled turn-on gate driver, voltage mode PWM controller with integrated 100 kHz oscillator, high voltage start-up bias circuit, bandgap derived reference, bias shunt regulator/error amplifier for loop compensation and fault protection circuitry.
  Compared to discrete MOSFET and controller or self oscillating (RCC) switching converter solutions, The TOP100 integrated circuit can reduce total cost, component count, size, weight and at the same time increase efficiency and system reliability. The TOP100 is intended for 100/110 VAC off-line Power Supply applications in the 0 to 60 W range and power factor correction (PFC) applications in the 0 to 110 W range. The TOP100 is also well suited for Telecom, Cablecom and other DC to DC converter applications in the 0-25 W range.
