产品概述

描述

The ST1843 and ST1845 ICs are rad-hard current mode PWM controllers providing an industry standard solution for the implementation of off-line or DC to DC fixed-frequency current mode control schemes with a minimal external part count. Its radiation hardness, hermetic packaging and its ESCC qualification make it an ideal choice for aerospace and other harsh environments.
  • 所有功能

    • Oscillator frequency guaranteed at 250 kHz
    • Trimmed oscillator for precise frequency control
    • Current mode operation to 500 kHz automatic feed forward compensation
    • Latching PWM for cycle-by-cycle current limiting
    • Internally trimmed reference with undervoltage lockout
    • High current totem pole output
    • Undervoltage lockout with hysteresis
    • Low start-up (<0.5 mA) and operating current
    • Ceramic hermetic package Flat-8 metallic lid floating
    • ST1843 50 krad (Si)
    • ST1845 100 krad (Si)
    • SEL free @ 120 MeV/cm2/mg at 125 °C
    • ESCC qualified as 9108/020 and 9108/021
