TS19501CB10H is a single channel LED driver of low-side-current sense. This device can operate in DCM, BCM and CCM mode with full protection and diagnostics. This device is fully dedicated and suitable for automotive headlight. This controller supports typical topologies such as Boost, Buck-Boost and SEPIC.
Output current regulation is based on average current mode control supervised by a control loop. The fault flag is connected to pull-up resistor from VDC for highlighting the information of fault and fault status flag is latched by the timer when output is low.
