SG1843 - CURRENT MODE PWM CONTROLLER

Download the SG1843 datasheet PDF. This datasheet also covers the SG1842 variant, as both devices belong to the same current mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The SG1842/43 family of control IC's provides all the necessary

Key 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. Oscillator discharge current is trimmed to less than ±10%. The SG1842/43 has undervoltage lockout, current limiting circuitry and start-u.
