Current Mode PWM Controller 1A 8-Pin FPAK T/R
The ST1843HR and ST1845HR ICs are rad-tolerant current mode PWM controllers providing an industry standard solution for the implementation of provides the off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count.Its radiation hardness and hermetic packaging makes it an ideal choice for aerospace and other harsh environments.
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 and operating current Hermetic package 50 and 100 krad (Si) SEL free @ 120 MeV/cm2/mg at 125°C
