Overview
SG1842/SG1843
Current Mode PWM Controller
Description
The SG1842/43 family of control IC's 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-bypulse current limiting and inherent protection of the power supply output switch.
The bandgap reference is trimmed to ±1% over temperature.
Oscillator discharge current is trimmed to less than ±10%.
The SG1842/43 has under-voltage lockout, current limiting circuitry and start-up current of less than 1mA.
The totem-pole output is optimized to drive...
