LV5011MD controls brightness of the LED by controlling a peak current of the internal MOSFET. 1. Peak current control LV5011MD detects the current of internal MOSFET as shown in the following diagram. The current that flows into MOSFET is a triangular wave shown in the diagram. The current peak value is determined by the relationship between the reference level and CS voltage. This relationship makes Power Factor Correction (PFC). CS voltage is used by internal comparator to compare to the reference level. LV5011MD controls the peak value of MOSFET current. Here, the reference level is lower value of either “REF_IN” or “VREF(0.605V)”.

Bleeder current cuircuit for TRIAC dimming LV5011MD contains the bleeder current circuit for TRIAC dimming. Please connect OUT2 to the external MOSFET gate and connect the resistor “Rd” to its drain. 2-1. Operating voltage setting OUT2 pin is controlled by setting value on ACS pin. When ACS pin voltage is below 3V, OUT2 is high and external FET is turned on. The bleeder operation threshold of the rectified AC is determined below. Vac_bleeder = R 3 R 4 3V R4 2-2. Bleeder current setting Bleeder current is set by Rd. Please calculate Rd value based on TRIAC dimmer. Waveforms diagram VAC voltage is Low, OUT2 is High voltage.

When UVLO operates, the power supply current of the IC is about 120A or lower. If VIN voltage is 9V or higher, then the IC starts switching operation. VIN voltage VIN voltage UVLOON (9Vtyp) UVLOOFF (7.3Vtyp) time Output stage on off on 3.2 OCP(Over Current Protection) CS pin is used to sense current in primary winding of transformer via internal HV MOSFET. This provides an additional level of protection in the event of a fault. If the voltage of the CS pin exceeds VCSOCP(1.9V typ.)(A), the internal comparator will detect the event and turn off the MOSFET. The peak switch current is calculated Iocp(peak) [A] = VCSOCP[V]/Rcs[] The VIN pin is pulled down to fixed level, keeping the controller latched off. The latch reset occurs when the user disconnects LED from VAC and lets the VIN falls below the VIN reset voltage,UVLOOFF(7.3V typ.)(B). Switching restarts when VIN rises to UVLOON(9V typ.)(C). CS voltage A C VCSOCP(1.9Vtyp) time VIN voltage B UVLOON(9Vtyp) UVLOFF(7.3Vtyp) time Output stage on off on No.A2201-9/10 LV5011MD 3.3 OVP(Over Voltage Protection) If the voltage of VIN pin is higher than the internal reference voltage VINOVP(27V typ.), switching operation is stopped. The IC(device) will not restart till reset voltage <7.3V and then rise to 9V. Please see OVP waveform chart. 3.4 OTP(Over Temperature Protection) The over temperature protection stops the switching operation of the IC in case the junction temperature reaches 165°C (typ.)(A). The IC starts switching operation again when the junction temperature is 135°C (typ.) (B) or lower. Please see OTP waveform chart.
