FR9708
Production
24V, 1.5A, 1.2MHz LED Driver with Dimming Control
產品說明
The FR9708 is a current mode, control LED driver IC. It provides wide 2.8V to 24V input voltage range and 1.5A output current capability.
The FR9708 includes a PWM dimming input that can accept an external control signal with a duty ratio of 5% to 100% and PWM dimming is from 100Hz to 50kHz(Follow EN turn-on delay time). It also supports 0.65V to 1.2V analog dimming input which can be used for linear dimming of the LED current.
The FR9708 fault protection includes current limit, input OVP, UVLO and thermal shutdown. The soft-start function prevents inrush current at turn-on. Internal compensation function reduces external compensatory components and simplifies the design process.
