TLD60981EPXUMA2

TLD60981EPXUMA2 is a multitopology single-channel DC-DC controller. The output current is regulated by means of peak current control loop. An internal slope compensation is used to avoid sub-harmonic oscillation at high duty cycle. The current accuracy is better than 3.5% (with no analogue adjustment applied) over the operating temperature range. A rail to rail current sense amplifier provides flexibility on the topology choice needed to supply LED string with more than 20 white LED (upto 70V at output). The switching frequency can be adjusted from 100kHz to 500kHz using an external resistor. A synchronization with an external clock is possible. The controller incorporates even a spread spectrum modulator to achieve easy fulfilment of electromagnetic emission standards. This controller is mainly used in LED driver for front light module, rear light module, interior light and voltage regulator applications.
