功能:
・4ch LED constant current driver and DC/DC converter・Maximum LED Current: 150mA
・LED Feedback Voltage: 0.37V (@NADIM=2.62V), so lower heat. Adjustable Feed Back Voltage by following LED Current setting.
・±2% LED current accuracy (NADIM=2.62V, when each LED is set to 100mA)
・Analog current (Linear) dimming at NADIM pin
・LED pin rating 60V
・Individual detection and individual LED OFF for both open and short circuits
・Built-in ISET pin short-circuit protection circuit
・Set Soft-Start time byexternal capacitor.
・FET’s Gate (N pin) is driven by 5.8V swing
・Built-in Vout discharge circuit for shutdown
・Built-in Vout overvoltage protection (OVP) / reduced voltage protection (SCP) circuit
・Adjustable LED Short Protection Voltage by LSP terminal
・HSOP20, HTSSOP-B24 package with high heat radiation efficiency
