Description
CS5106
The CS5106 is a fixed frequency,
current mode controller with one
single NFET driver and one dual
FET, synchronous driver. The syn-
chronous driver allows for
increased efficiency of the main iso-
lated power stage and the single
driver allows the designer to devel-
op auxiliary supplies for controller
power as well as secondary side
house keeping. In addition,
because the synchronous drivers
have programmable FET non-over-
lap, the CS5106 is an ideal con-
troller for soft-switched converter
topologies.
The CS5106 is specifically designed
for isolated topologies where speed,
flexibility, reduced size and
reduced component count are
requirements. The controller con-
tains the following features:
Undervoltage Shutdown,
Overvoltage Shutdown,
Programmable Frequency,
Programmable Synchronous Non-
Overlap Time, Master/Slave
Clocking with Frequency Range
Detection, Enable, Output
Undervoltage Protection with
Timer, 20mA 5V Output, 80ns
PWM propagation delay, and
Controlled Hiccup Mode.
The CS5106 has junction tempera-
ture and supply ranges of -40C to
125C and 9V to 16V respectively
and is available in the 24 lead SSOP
package.
