SI9114A - High-Frequency Switchmode Controller

Description

The Si9114A 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%.

Si9114A Vishay Siliconix High-Frequency Switchmode Controller FEATURES D 15- to 200-V Input Range D Current-Mode Control D Internal Start-Up Circuit D Latched SHUTDOWN D Soft-Start D 1.8-MHz Error Amp DESCRIPTION The Si9114A 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%. An oscillator sync output allows converters to be synchronized in phase as well as in frequency, in a master/slave configuration. The output inverter can typically source 500 mA and sink 700 mA. Shoot-through current is all but eliminated to minimize supply current requirements.
