NCP5602
The physical address of the NCP5602 is 1001 111X, the
X being the Read/Write identifier as defined by the I2C
specification. Since the NCP5602 does not return data, the
first byte of the I2C frame shall be 1001 1110 ($9E) as
depicted in Table 2.
Table 1. NCP5602 Physical I2C Address
To set up a new output current value, a full frame shall
be sent by the MCU. The frame contains three consecutive
bytes and shall fulfill the I2C specifications:
First byte : I2C address 3 $9E
Second byte : internal register address 3 $01
Third byte : output current value 3 $00 to $1E
(0 mA to 30 mA, Assuming Rext = 10 k W )

The waveforms given in Figure 9 illustrate a typical
output current update.

Dimming
The built ? in I2C interface provides a simple way to
accurately control the output current flowing in the two
LED. Such dimming is active under the NORMAL mode
only and the LED2 current cannot be adjusted when the
ICON mode is active.
The internal register LED ? REG[0..7] is set up by the
content of the SDA byte sent by the external MCU as
depicted in Table 2. For typical application, the 60 m A
reference current forced by the external resistor is
multiply by 16 to get a 1.0 mA/step in the output
LED. The waveforms given Figure 10 illustrate a normal
programming sequence.

The DC ? DC converter is switched OFF and the two LED
