The output current generated by the two channels are independent and they are regulated by means of a peak current control loop. An internal slope compensation is used to avoid sub-harmonic oscillation at high duty cycle (e.g. higher than 50%). The current accuracy is better than 3.5% (with no analog adjustment applied) over the operating temperature range. A rail to rail current sense amplifiers provide flexibility on the topology choice needed to supply LED string with more than 20 white LED (up to 70 V at output). The switching frequency can be adjusted from 100 kHz to 500 kHz using an external resistor. A synchronization with an external clock is also possible. The device incorporates even a spread spectrum modulator to achieve easy fulfilment of electromagnetic emission standards. Each channel of TLD6098-2ES can drive an external PMOS for dimming and protection. For this purpose each channel of TLD6098-2ES incorporates even a PWM generator controlled by an analog voltage on DC/PWM1,2 pin. The generated PWM signal has the duty cycle adjustable from 0 to 100% with 10 bits of resolution and the frequency range programmable from 150 Hz to 750 Hz. On the same DC/PWMI1,2 pin the digital PWM signal can also be used. Product validation Qualified for automotive applications. Product validation according to AEC-Q100. Datasheet 2 Rev.1.10 2021-09-30
