Note1) Absolute maximum ratings represent the values which cannot be exceeded for any length of time. 

Note2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded.  Please contact us for the further details. 

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

**LV5011MD** 

## **Functional description** 

LV5011MD is an LED driver IC that operates directly from the rectified AC voltage. 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)”.

The peak value of MOSFET current (Ipk) is determined by : 

> In the case of “REF_IN < VREF(0.605V)” → _Ipk_  _REF_  IN Rcs_ .0605 _V_ 

> In the case of “REF_IN > VREF(0.605V)” → _Ipk_  _Rcs_ 

## **2. 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  3 _V R_ 4 

## **2-2. Bleeder  current setting** 

Bleeder current is set by Rd. Please calculate Rd value based on TRIAC dimmer.

## **3.1 UVLO(Under Voltage Lock Out)** 

If VIN voltage is 7.3V or lower, then UVLO operates and the IC stops. When UVLO operates, the power supply current of the IC is about 120  A or lower. If VIN voltage is 9V or higher, then the IC starts switching operation.

## **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).

## **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.
