・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
