TCS5104
1.0MHz，2A Synchronous Step-Down LED Driver
产品描述
The is a constant frequency, current mode PWM step-down LED driver with 2A output current and 1.0MHz switch frequency. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the LED current. The feedback voltage is 0.1V typically. The device also integrates many protection features included input OVP, cycle-by-cycle current limit, over temperature protection.
