ICL1502 is a dual-channel high-voltage linear LED constant-current driver chip, which can support DC dimming and PWM dimming, and has the function of line voltage compensation. It is internally integrated with 500V high-voltage MOS.

The output current of the two channels can be set by external resistors RISET1& RISET2, and the current can be in the range of 5mA~200mA.

Make any adjustment. In addition, 0V/3.3V or 0V/5V PWM(Pulse Width)

Modulation) dimming, and 0V~3.3V DC dimming, providing

The elastic brightness level mode of LED light emission.

ICL1502 provides two channels with excellent line voltage compensation function via common VD pin; Built-in linear over-temperature protection function can effectively prevent the system from being damaged due to excessive temperature.

The whole ICL1502 system has the advantages of simple periphery, flexible application, high reliability, small volume and low system cost. Appropriate packaging technology can be applied to all kinds of LED lamps.
