Product overview

Description

The HVLED002 control IC provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes to implement LED drivers. Internally implemented circuits include a trimmed oscillator for the precise duty cycle control, undervoltage lockout, a precision reference trimmed for accuracy at the error amplifier input, a PWM comparator which also provides current limit control and a totem pole output stage designed to the source or sink high peak current. The output stage, suitable for driving N-channel MOSFETs, is low in the off-state.

  • All features

    • Trimmed oscillator for precise frequency control
    • Oscillator frequency guaranteed at 250 kHz
    • Current mode operation to 500 kHz
    • Latching PWM for cycle-by-cycle current limiting
    • Internally trimmed reference with undervoltage lockout
    • High current totem pole output
    • Undervoltage lockout with hysteresis
    • Low start-up and operating current
