The SG1524B is a pulse width modulator for switching power supplies, that gives improved performance over industry standards, like the SG1524. This is a direct pin-for-pin replacement for the earlier device, and combines advanced processing techniques and circuit design to provide improved reference accuracy, and extended common mode range at the error amplifier and current limit inputs. A DC-coupled flip-flop eliminates triggering and glitch problems, and a pulse width modulator data latch prevents edge oscillations. The circuit incorporates true digital shutdown for high speed response, while an under voltage lockout circuit prevents spurious outputs when the supply voltage is too low for stable operation. Full double-pulse suppression logic insures alternating output pulses when the shutdown pin is used for pulse-by-pulse current limiting. SG1524B is specified for operation over the full military ambient temperature range of –55 °C to 125 °C. SG2524B is characterized for the industrial range of –25 °C to 85 °C, and SG3524B is designed for the commercial range of 0 °C to 70 °C
