Dimmable LED controller supports multiple topologies
Available in a compact MSOP-10EP package, the TS19501CB10H is a single channel LED driver with low-side-current sense and a device temperature grade 1 (-40 to 125°C). It supports typical topologies such as boost, buck-boost and Single-ended primary-inductor converter (SEPIC) and operates in continuous conduction mode (CCM), discontinuous conduction mode (DCM) and boundary conduction mode (BCM).

The jitter function provides an effective spread spectrum to reduce EMI. Output current regulation is based on average current mode control supervised by a control loop. The fault flag is connected to a pull-up resistor from V DC. The fault status flag is latched by the timer when output is low.

The LED controller is optimised for automotive lighting applications but can also be used for LED applications that use buck-boost topology.
