Description

AW36604 is a 4-channel, linear current sink LED/IR driver with an ultra-low dropout voltage. Each channel drives a high brightness LED string with a current of up to 240mA in DC, and 350mA in 330μs pulse. The output current is configured by the external resistor connected to the RSET pin and ground. The LED pins can support high voltage application up to 25V for multiple LED string applications. AW36604 provides EN pin which can be used for hardware enable and ON/OFF dimming PWM signal input. AW36604 has an over temperature shutdown function, which prohibits LED output when the chip temperature exceeds 150°C.
