SG1843J/883B規(guī)格書詳情

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)
