功能:
- 4ch LED constant current driver and DC/DC converter
- Maximum LED Current: 150mA
- LED Feedback Voltage: 0.45V (@ILED=150mA)
so lower heat. Adjustable Feed Back Voltage
by following LED Current setting. - ±2% LED current accuracy (ADIM=2.5V,
when each LED is set to 100mA) - Analog current (Linear) dimming at ADIM 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
- 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 - SOP16 package
