概览

The ISL738840ASEH is a high-performance, radiation hardened drop-in replacement for the popular 28C4x and 18C4x PWM controllers suitable for a wide range of power conversion applications including boost, flyback and isolated output configurations. Fast signal propagation and output switching characteristics make these ideal products for existing and new designs. Features include up to 13.2V operation, low operating current, 90µA typical start-up current, adjustable operating frequency to 1MHz, and high peak current drive capability with 50ns rise and fall times.

  • QML qualified per MIL-PRF-38535 requirements
  • 1A MOSFET gate driver
  • 90µA typical start-up current, 125µA maximum
  • 35ns propagation delay current sense to output
  • Fast transient response with peak current-mode control
  • 9V to 13.2V operation
  • Adjustable switching frequency to 1MHz
  • 50ns rise and fall times with 1nF output load
  • Trimmed timing capacitor discharge current for accurate dead time/maximum duty cycle control
  • 1.5MHz bandwidth error amplifier
  • Tight tolerance voltage reference over line, load, and temperature
  • ±3% current limit threshold
  • Pb-free available (RoHS compliant)
  • Radiation acceptance testing - ISL73884xASEH
    • LDR (0.01rad(Si)/s): 50krad(Si)
  • Current mode switching power supplies
