A very efficient constant current controller IC for low cost non-dimmable LED lighting applications: TS19706CS.

The TS19706CS is configurable for either isolated primary side Flyback regulation or non-isolated buck-boost current regulation topologies.

Integrated 630 V Power MOSFET and active power factor correction in Flyback mode reduces the external components required and BOM for implementation.

The IC achieves high power factor correction and low total harmonic distortion (THD) with Boundary Conduction Mode (BCM) operation.

The line and load regulation of LED current are easily maintained to <± 3%. TS19706CS also provides over temperature protection, VCC overvoltage protection, and system output open and short circuit protection.

An integrated solution using built-in switch mode constant current (CC) and constant voltage (CV) regulation for smart LED lighting applications: TS19340CS14.

The integrated PWM and linear dimming functions allow the designer to replace many external discrete components used for dimming schemes.

The PWM frequency is configurable from 100 Hz to 10 kHz through selection of the compensation capacitor. The linear dimming cut off voltage is configurable using a resistor divider at the CCO pin.

High performance, constant current PWM controller LED drivers with integrated high voltage synchronous switching power MOSFETs: TS19751xCS.

Excellent line and load regulation, high accuracy, and efficiency are achieved by peak-sensing, current-mode buck conversion.

Pulse-by-pulse waveform analysis allows a compensated loop response much faster than traditional solutions, resulting in improved dynamic load response.

The TS19751xCS provide a number of built-in protection features minimizing external component count, simplifying EMI design, and lowering total bill of material cost. The integrated current limit function enables optimized transformer design in universal off-line applications over a wide input voltage range.
