  • Direct Type/ Local Dimming (Conventional TV power + Boost + LED driver)
    In this topology: the UCC28051 is a boost transition mode (TM) power factor corrector (PFC): which can rectify an AC input line voltage to 380V DC; the resonant LLC stage UCC25600 regulates the output to 24V/2A for an audio amplifier with feedback to the LLC controller: and 48V for the LED driver input. The flyback with UCC28610 in parallel generates 5V/3A for the system board and 5V/1A for standby power. In the LED driver stage: the 48V input voltage requires another front end boost stage to boost the output voltage to 80V: which connects to the eight-channel TLC5960 with 20LEDs at 120mA per string.This technique is the most common type of current LED backlight; the LLC design is easily implemented. The intelligent headroom voltage monitor (oriHVM™) automatically minimizes the power loss caused by the LED forward voltage change. Only a single additional resistor regulates the boost dc-dc output voltage.

LM393M Frequently Asked Questions (FAQ)

  • The maximum voltage that can be applied to the input pins is the supply voltage (Vcc) + 0.3V. Exceeding this voltage can cause damage to the device.

  • To prevent oscillation, ensure that the input voltage difference is greater than the input offset voltage (typically 2mV), and that the output is properly terminated with a pull-up resistor.

  • The minimum input voltage difference required for a valid comparison is typically 2mV, but this can vary depending on the specific application and noise conditions.

  • No, the LM393M is a comparator, not an amplifier. It is designed to provide a digital output based on the comparison of two input voltages, not to amplify a signal.

  • When the input voltages are equal, the comparator output will be undefined. To handle this case, you can add hysteresis to the input signals or use a Schmitt trigger configuration.
