Description
The IRS2548D is a fully integrated, fully protected 600V LED or switched mode power supply control IC with
integrated PFC control for a Boost pre-regulator. The IRS2548D is based on the popular IRS2168D
electronic ballast control IC re-designed for use in LED driver or half-bridge power supply applications. The
PFC circuitry operates in critical conduction mode and provides high PF, low THD and DC bus regulation.
The IRS2548D features include programmable minimum run frequency and adjustable oscillator frequency
that can be driven by an opto isolator or other feedback circuit in a feedback loop for frequency modulation in
resonant systems. The IRS2548D also includes PFC over-voltage and over-current protection, half bridge
over current protection and a logic level enable input that can be used for PWM dimming in LED drivers or
general burst mode operation.
