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.
