A711

www.addmtek.com DESCRIPTION The A711 is a high voltage, low dropout current regulator for high power LED, that the maximum output current can be up to 1.1Amp. The output current was decided by an external resistor. The output sink current could be disabled via OE pin. PWM dimming function could also be controlled by OE pin. TO-263 package is available for good power dissipation ability. Build-in thermal protection to prevent the chip from over heat damage, and adequate thermal pad PCB area is required to control the junction temperature below 125°C. TYPICAL APPLICATION CIRCUIT 5V~50V CBP Enable/ PWM Dimming RSET OE ISET VDD A711 GND OUT CO A711 1.1A HIGH VOLTAGE ADJUSTABLE CURRENT REGULATOR WITH ENABLE CONTROL FEATURES 0.8V Output Drop-out Voltage at 1.1Amp. 1.1Amp.
