Si9114 Datasheet High-Frequency Switchmode Controller

Manufacturer: TEMIC Semiconductors (now Microchip)

Overview: Si9114 High-Frequency Switchmode Controller TEMIC Siliconix.

General Description

The Si9114 is a BiC/DMOS current-mode pulse width modulation (PWM) controller IC for high-frequency dc/dc converters.

Single-ended topologies (forward and flyback) can be implemented at frequencies up to 1 MHz.

The oscillator has an internal divide-by-two that limits the duty ratio to 50%.

Key Features

  • 15- to 200-V Input Range.
  • Current-Mode Control.
  • Internal Start-Up Circuit.
