RT8565
Small Package, High Performance, Diode Embedded, Asynchronous Boost, 6 WLEDs Driver
General Description
The RT8565 is a high efficiency LED driver IC capable of driving 6 LEDs.
The RT8565 integrates 26V/0.
9A power switch with an internal
Schottky diode.
The RT8565 is a current mode boost converter which is fixed at 600kHz operating frequency and has a wide input voltage range from 2.
8V to 4.
5V.
The LED current is set with an external resistor and the feedback voltage is regulated to 200mV.
During operation, an internal 6-bit DAC is used for brightness control.
Users can easily configure up to 64 steps of LED current via the EN pin.
During brightness dimming, the RT8565 does not burs...
