Product Summary

The SG2843D is the control IC which 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.

Parametrics

SG2843D absolute maximum ratings: (1)Supply Voltage (ICC < 30mA): Self Limiting; (2)Supply Voltage (Low Impedance Source): 30V; (3)Output Current (Peak): ±1A; (4)Output Current (Continuous): 350mA; (5)Output Energy (Capacitive Load): 5μJ; (6)Analog Inputs (Pins 2, 3): -0.3V to +6.3V; (7)Error Amp Output Sink Current: 10mA; (8)Power Dissipation at TA = 25°C (DIL-8): 1W; (9)Operating Junction Temperature Hermetic: 150℃; (10)Storage Temperature Range: -65 to +150℃; (11)Lead Temperature (Soldering, 10 Seconds): 300℃.

Features

SG2843D features: (1)Optimized for off-line control; (2)Low start-up current( ＜1mA ); (3)Automatic feed forward compensation; (4)Trimmed oscillator discharge current; (5)Pulse-by-pulse current limiting; (6)Enhanced load response characteristics; (7)Under-boltage lockout with 6V hystersis; (8)Double-pulse suppression; (9)High-current totem-pole output.
