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.
The high-voltage DMOS transistor allows the IC to interface directly to bus voltages up to 200 V.
Other features include a 1.
5% accurate voltage reference, 1.
8-MHz (min) bandwidth error amplifier, shutdown logic c...
