Application Information
Start-up Current
The typical start-up current is around 45
μA. Very low start-up current allows the PWM controller to increase the
value of start-up resistor and then reduce the power dissipation.
UVLO(Under Voltage Lockout)
A hysteresis UVLO comparator is implemented in TS19730. The turn-on and turn-off thresholds level are fixed at
17.5V and 8V respectively. This hysteresis shown in Fig.3 ensures that the start-up capacitor will be adequate to
supply the chip during start-up. For quick start-up of the LED driver, the start-up resistor should be matched with
the start-up capacitor.

LEB(Leading-Edge Blanking)
Each time the power MOSFET is switched on, a turn-on spike will inevitably occur at the sense resistor. To avoid
fault trigger, a 400ns leading-edge blanking time is built in. Conventional RC filtering can therefore be omitted.
During this blanking period, the current-limit comparator is disabled and cannot switch off the gate driver.
OCP(Over Current Protection)
The TS19730 has built-in cycle by cycle over current protection function on CL pin. As the CL pin voltage is larger
than VOCP (0.3V), the gate output will be turned off immediately to avoid the driver board to be burned out.
