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%.
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 typicallysource 500rnA and sink 700 rnA.
Shoot-through current is all but eliminated to
