The LYTSwitch™-7 family is ideal for single-stage, high PF, constant
current LED dimmable applications.
The family incorporates a high-voltage MOSFET with a variable on-time
CrM controller. Extensive protection features with minimum external
components provide industry leading power density and functionality.
The CrM operation results in low turn-on losses and reduces cost of
output diode (slower reverse-recovery type can be used).
LYTSwitch-7 devices are suitable for applications from 4 W to 22 W.
See Graph 1 for selection guidance (based on typical inductance). For
more information, see Application section. LYTSwitch-7 peak current
mode operation is suitable for TRIAC applications without the need for
an active bleeder.
