Description
The SG1842/43 family of control ICs provides all the necessary features to implement off-line fixed frequency, current-mode switching power supplies with a minimum number of external components.
Current-mode architecture demonstrates improved
line regulation, improved load regulation, pulse-by pulse current limiting and inherent protection of the power supply output switch. The bandgap reference is trimmed to ±1% over temperature.
Features
? Optimized For Off-Line Control
? Low Start-Up Current (<1mA)
? Automatic Feed Forward Compensation
? Trimmed Oscillator Discharge Current
? Pulse-By-Pulse Current Limiting
? Enhanced Load Response Characteristics
? Under-Voltage Lockout with 6V Hysteresis (SG1842
only)
? Double-Pulse Suppression
? High-Current Totem-Pole Output (1A Peak)
? Internally Trimmed Bandgap Reference
? 500kHz Operation
? Undervoltage Lockout
SG1842 - 16 volts
SG1843 - 8.4 volts
? Low Shoot-Through Current <75mA Over
Temperature
Application
? Available To MIL-STD – 883, ? 1.2.1
? Available to DSCC
- Standard Microcircuit Drawing (SMD)
