GENERAL DESCRIPTION
The evaluation system is composed of a motherboard and a
daughterboard. The motherboard provides the I2C® signals
from the computer USB port and generates the I/O voltages
and digital high and low signals for the daughterboard. For
temperature measurement, the daughterboard can either be

Before changing settings in the ADP1655 registers, the I C
interface has to be enabled by clicking the I2C_EN button (the
button turns green and the I2C_EN LED on the motherboard
lights up) in Section 7 of the user registers window (see Figure 11).
To program the LED current, set Assist Light Current and
Flash Current in Section 3 and click the Program 0x03 button.
For USB powered demonstrations, a minimum Flash Current
setting of 200 mA should be used to avoid exceeding the USB
current source capability of 500 mA.

Click the Strobe button in Section 7 to initiate Flash.
The length of the Flash event can be programmed by setting the
value under S/W Flash Timer in Section 5 and clicking the
Program 0x02 button. To initiate Flash again, reprogram
Register 0x04 and click Strobe again. STROBE can be enabled
either from the user registers window by clicking Strobe under the
Input Controls (Section 7) or from the hardware STROBE button
on the motherboard. To use the hardware button, strobe button
has to be enabled in Section 8 of the user registers window.
Set I2C_EN in Section 7 of the user registers window.
In Section 2, set Output Mode to Flash and set 1- Output

Note that it is recommended to use an external power supply
for this operation because fixed Flash current values are set to
320 mA and 500 mA for two and one LED(s), respectively.
Otherwise, the USB current sourcing limitation of 500 mA
will be exceeded. Use the I2C_EN, EN1, and EN2 buttons in

Set I2C_EN low (button becomes gray).
Set EN1 high (green). The red indicator LED (D4) should

Set EN2 high (green) to initiate Flash.
ENABLING UP TO 500 MA LED CURRENTS
The ADP1655 limits LED output current to 400 mA by default
if two LEDs are used. In one-LED operation, currents of up to
500 mA are automatically allowed.
In I2C interface mode, it is possible for you to enable up to
500 mA of output currents in two-LED operation.

Click the Program 0x04 button.
The torch current level can be programmed by setting the
desired value under Assist Light Current in Section 3. To light
up the LEDs, click the Torch button in Section 7. In addition,
the TORCH hardware button on the motherboard can be used
by clicking torch button in Section 8.
Set I2C_EN low (button becomes gray).
Click the Torch button in Section 7 (input controls) to
light up the LEDs in torch mode, or use the TORCH
hardware button on the motherboard, which must first be
enabled via the torch button in Section 8 of the user
registers window.
Timeout is hardware limited to a maximum of 850 ms. Desired
Flash timeouts can be set by changing the setting under the
S/W Flash Timer box in Section 5 and clicking the Program
0x02 button.
FAULT DETECTION STATUS
Faults in Section 4 is used to read back the fault detection
status from the ADP1655. Click Read 0x05 to view information
about the fault. I2C_EN must be high (green) to be in read
mode. Overvoltage fault occurs when the output voltage is
greater than 9.5 V (typical). A timeout fault occurs when the
STROBE button on the evaluation board is pressed longer than
the programmed timeout duration in strobe level-sensitive
mode. A thermal fault occurs when the device junction
temperature is greater than 150°C. A short-circuit fault occurs
if the LED_OUT pin remains grounded during startup.
LED AMOUNT DETECTION
The amount of LEDs is detected by the ADP1655 and the
detection is enabled from 1 - LED Amount ON in Section 3.
The amount of LEDs is measured during the start of either
Flash or torch, and the default level for whether one or two
LEDs are connected to the output is set at 4.3 V (typical).
Detection level can be changed to 4.3 V plus VREF offset using
the Vref Offset box.
HISTORY
Whenever you issue a command (both read and write), it is
recorded in the History tab, shown in Figure 12. To display the
History dialog box, click the History tab on the evaluation
software GUI. You can copy and paste the history into a file for
future evaluation purposes.

however, the ribbon cable provided with the evaluation kit must
be used to connect the motherboard and the daughterboard
because the Cypress CY68013A is not rated at −40°C.
The Cypress Semiconductor Corporation CY68013A provides
the USB interface and I2C signals. The selected I2C frequency is
400 kHz. The EEPROM U5 M24C64 provides the USB address
of the board. The interface VDDIO voltage is adjusted using
evaluation software GUI and is set to 1.9 V by default.

Figure 14. Daughterboard
The ADP1655 evaluation daughterboard is designed to quickly
evaluate key parameters of the ADP1655 IC. The board layout
footprint is extended so that parts can be exchanged and
headers are available to measure currents using a current probe
or ammeter.
Connect a power supply or Li-Ion battery with 2 A capability to
VIC. Up to 1.8 A can be drawn from the battery; therefore,
short, thick cables are recommended to minimize the IR drops.
A high current can cause a big IR drop, and VIN of ADP1655 can be
low enough to put the part into UVLO.
ADP1655 DAUGHTERBOARD BOTTOM SIDE
IQ
IQ is the supply current and can be measured by using an
ammeter across J7. On the bottom side of the ADP1655
daughterboard, Resistor R7, Resistor R9, and Resistor R13, as
well as IC U20 and IC U22, are connected to the supply voltage,
which affect IQ measurement. Follow the instructions described
in Figure 15 for ADP1655 shutdown and standby mode current
measurements.
IL
IL is the inductor current and can be measured by using a current
loop across J13.
ILED
ILED is the LED current and can be measured by using an
ammeter or current loop across J8.
