Illumination and Flash
RGB-LED Driver
Description
IR2E46Y incorporates the illumination driver and the flash
driver for an RGB-LED, and is equipped with the step-up
DC/DC converter.
This product is optimum for use as the RGB-LED driver IC
for PDA and cellular phone applications, etc.
Features
1.Power supply: 2.7 V to 4.5 V
2.Supports I2C-bus interface
The I2C address extension function enables simultaneous
controlling of four devices.
3.SCL pin and SDA pin are installed with noise filters.
4.Sink-type variable constant current driver for RGB-LED
(maximum current 155mA x 3ch
Stroboscopic mode: 0mA to 155mA
(32 steps per output, 5.0mA STEP)
Illumination mode: 0mA to 31.5mA
(64 steps per output, 0.5mA STEP)
5.VF control circuit embedded (VDD to 13V)
6.LED brightness adjustment circuit embedded (16 steps,
PWM control)
7.Stroboscopic timer embedded
8.Independent RGB control output enable circuit embedded
9.Current slope control circuit embedded
10.Voltage/current PWM control type step-up DC/DC converter
circuit embedded (oscillatory frequency 1.2 MHz)
11.Low ON resistance switch (0.2Ω TYP.)
12.SW transistor overcurrent protection circuit embedded
13.Voltage reference embedded
14.Stand-by circuit embedded
15.Power-on-reset circuit embedded
16.UVLO circuit embedded
17.Digital soft-start circuit embedded
18.Thermal shutdown circuit embedded
Agency approvals/Compliance
1. Compliant with RoHS directive(2002/95/EC)
Applications
1.Torch light and illuminations
(RGB LED)
