The application circuit of driving 5 white light LEDs
TPS60230 can drive 5 25mA white light LEDs at most; TPS60231 can drive 3 25mA white light LEDs at most; the main technology features of TPS60230/TPS60231 are shown as follows.①the brightness of the white light LED can be controlled by PWM; ②it has the 1 and 1.5 time shift modes of self-adaption, and it can get high efficiency; ③the shift frequency is 1MHz; ④the working input voltage range is 2.7~6.5V; ⑤it contains the soft starting circuit, by which the transient state influx current can be impeded; ⑥low input wave and low EMI(electromagnetic disturbance).
