LYT6078C – LED Driver IC with PowiGaN Technology for Flicker-Free Output in Smart Lighting Applications

Power Integrations has added a new member of the LYTSwitch-6 family of safety-isolated LED drivers for smart lighting applications. Named LYT6078C, this new LYTSwitch-6 IC uses Power Integrations’ PowiGaN gallium nitride (GaN) technology and promises to deliver enhanced performance and efficiency.

Housed in the small InSOP-24 surface-mount package, the LYTSwitch-6 ICs have an advanced thermal foldback system for protection. This reduces output power to limit device temperature during abnormal conditions, while still providing light output. The PowiGaN-based LYT6078C IC comes with a 750 V power switch and delivers a flicker-free output which is up to 90 W. With the PFC stage and the LYTSwitch-6 LED driver, this ensures to increase the efficiency up to 90%.

Besides this, the LYTSwitch-6 ICs also incorporate Power Integrations’ FluxLink communication technology that enables secondary-side control without the need for an optocoupler and provides better than ±3% CV and CC regulation across the line, load, temperature, and manufacturing. The LYTSwitch-6 ICs exhibit fast transient response and easily support pulse-width-modulation (PWM) dimming.

With LYT6078C IC and Power Integrations’ HiperPFS-4 PFS7624C PFC controller, it can provide high efficiency when driving a 48 V LED string at 1350 mA from a 220 VAC to 277 VAC input. The system power consumption in standby mode is less than 80 mW thereby offering great flexibility in designing lighting controls and particularly dim-to-off circuits.
