DESCRIPTION

· Integrated PFC, ballast control, and half-bridge driver in a single IC.
· Designed for electronic ballast applications.
· Compact 8-pin SOIC package, lead-free.

FEATURES

· Critical-conduction mode boost-type PFC.
· Internal VBUS sensing, regulation, and PFC loop compensation.
· Programmable PFC over-current, preheat time, frequency, ignition ramp time, and run frequency.
· Half-bridge non-ZVS and over-current protection.
· Voltage-controlled oscillator (VCO) analog input.
· Latched EOL window comparator and internal EOL fault timer.
· Fixed dead-time (1.7 µs typical).
· DC bus under-voltage reset and lamp insert auto-restart.
· Micro-power start-up current and under-voltage lock-out mode.

APPLICATIONS

· Electronic ballast systems.
