DESCRIPTION
The Si9118/Si9119 are a BiC/DMOS current-mode pulse
width modulation (PWM) controller ICs for high-frequency
dc/dc converters. Single-ended topologies (forward and
flyback) can be implemented at frequencies up to 1 MHz.
The controller operates in constant frequency mode during
the full load and automatically switches to pulse skipping
mode under light load to maintain high efficiency throughout
the full load range. The maximum duty cycle is easily
programmed with a resistor divider for optimum control.
The push-pull output driver provides high-speed switching to
external MOSPOWER devices large enough to supply 50 W
of output power. Shoot-through current for internal push-pull
stage is almost eliminated to minimize quiescent supply
current.

The high-voltage DMOS transistor permits direct operation
from bus voltages of up to 200 V. Other features include a
1.5 accurate voltage reference, 2.7 MHz bandwidth error
amplifier, standby mode, soft-start and undervoltage lockout
circuits.
The Si9118/Si9119 are available in both standard and lead
(Pb)-free packages.
