Descrizione

Traduzione AI

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. LYTSwitch-7 peak current mode operation is suitable for TRIAC applications without the need for an active bleeder.

LYTSwitch-7 is a SO-8 package LED driver IC family designed for non-isolated buck applications. The LYTSwitch-7 family provides high efficiency, high power factor and accurate LED current regulation. It incorporates a high-voltage 725 V power MOSFET and a control engine to switch the MOSFET in critical conduction mode (CM) with variable on-time and variable frequency which also helps achieve low EMI, and low THD. The controller also integrates protection features such as input and output overvoltage protection, thermal fold-back, over-temperature shutdown, output short-circuit and over-current protection. The controller also allows natural dimming with only the addition of a damper resistor and an RC network for damping the input current ringing when the TRIAC turns on.
