The AHK3296 operates directly from a 2.7V to 5.5V power source and enables and controls the current to the LEDs. LED current is individually controlled through integrated current sinks powered from an external power supply. Low resistance and lowdrop out voltage current sinks allow the LEDs to operate very close to the input supply voltage, eliminating the need for an additional noisy boost power supplies. The AHK3296 requires only one external component: one 1μF ceramic input capacitor (CIN). The AHK3296 can drive six constant output sinks (D1 to D6) each with a maximum current of up to 20.6mA which is set internally. Skyworks S2Cwire serial interface enables the AHK3296 and changes the current sink magnitudes for main group (D1-D3) and sub group (D4-D6) through the ENM and ENS pins respectively, thereby changing the LED currents. S2Cwire Serial Interface The LED output current of the AHK3296 is controlled by Skyworks S2Cwire serial interface. Since the LED current is programmable, no PWM or additional control circuitry is needed to control LED brightness. This feature greatly reduces the burden on a microcontroller or system IC to manage LED or display brightness, allowing the user to 8 I REF GND DAC “set it and forget it.” With its high-speed serial interface (1MHz data rate), the LED current can be changed quickly and easily. Also the non-pulsating LED current reduces system noise and improves LED reliability. If both the main (D1, D2 and D3) and sub (D4, D5 and D6) groups are to be programmed with the same current level per channel they can share a common GPIO microprocessor port. The S2Cwire interface relies on the number of rising edges to the ENS and ENM pins to set the registers. A typical write protocol is a burst of ENM and ENS rising edges, followed by a pause with ENM and ENS held high for at least tLAT (500μs). The programmed current is then seen at all current sink outputs. When ENM and ENS are held low for an amount of time longer than tOFF (500μs), the AHK3296 enters into shutdown mode and draws less than 1μA from the input and the internal data register is reset to zero. The AHK3296 serial interface reduces the LED current on each rising pulse of the enable inputs ENM and ENS. If the AHK3296 is in shutdown, the first rising edge of the ENM turns on all main channels D1-D3 to the maximum current level. The first rising edge of the ENS turns on all sub channels D4-D6 to the maximum current level.. Successive rising edges of ENM decrease the LED current for the main channels (D1-D3) and successive rising edges of ENS decrease the LED current for the sub channels (D4D6) as shown in Table 1 and Figure 1 for the AHK3296.

LED Selection The AHK3296 is specifically intended for driving white LEDs. However, the device design will allow the AHK3296 to drive most types of LEDs with forward voltage specifications typically ranging from 2.2V to 4.7V depending upon supply voltage. LED applications may include mixed arrangements for display backlighting, keypad display, and any other application that needs a constant current sink generated from a varying input voltage. Since the D1 to D6 constant current sinks are matched within 3% with negligible supply voltage dependence, the constant current channels will be matched regardless of the specific LED forward voltage (VF) levels. The low dropout current sinks in the AHK3296 maximize performance and make it capable of driving LEDs with high forward voltages. The six channels can be combined to obtain a higher LED drive current without complication. Shutdown Code vs. LED Current Since the current switches are the only power supplies for all loads, there is no leakage current when all sink switches are disabled. To activate the shutdown operation, both the ENM and ENS inputs for the AHK3296 should be strobed low for longer than tOFF (500μs). In this state, the AHK3296 typically draws less than 1μA from the input. All registers are reset to 0 in shutdown.

Capacitor Selection Equivalent Series Resistance Careful selection of the external capacitor CIN is important because it will affect turn-on time and transient performance. Optimum performance will be obtained when low equivalent series resistance (ESR) ceramic capacitor is used; in general, low ESR may be defined as less than 100mΩ. A value of 1μF for the input capacitor is a good starting point when choosing a capacitor. If the constant current sinks are only programmed for light current levels then the input capacitor size may be decreased. ESR is an important characteristic to consider when selecting a capacitor. ESR is a resistance internal to a capacitor that is caused by the leads, internal connections, size or area, material composition, and ambient temperature. Capacitor ESR is typically measured in milliohms for ceramic capacitors and can range to more than several ohms for tantalum or aluminum electrolytic capacitors. Capacitor Characteristics Ceramic composition capacitor is highly recommended over all other types of capacitors for use with the AHK3296. Ceramic capacitors offer many advantages over their tantalum and aluminum electrolytic counterparts. A ceramic capacitor typically has very low ESR, is lower cost, has a smaller PCB footprint, and is non polarized. Since ceramic capacitors are non-polarized, they are not prone to incorrect connection damage. 10 Ceramic Capacitor Materials Ceramic capacitors less than 0.1μF are typically made from NPO or C0G materials. NPO and C0G materials generally have tight tolerance and are very stable over temperature. Larger capacitor values are usually composed of X7R, X5R, Z5U, or Y5V dielectric materials. Large ceramic capacitors (i.e., larger than 2.2μF) are often available in low cost Y5V and Z5U dielectrics, but capacitors larger than 1μF are not typically required for AHK3296 applications.

Capacitors that are physically large will have a lower ESR when compared to an equivalent material smaller capacitor. These larger devices can improve circuit transient response when compared to an equal value capacitor in a smaller package size. Evaluation Board User Interface Table 2 indicates the function of each button or button combination. To power-on the evaluation board, connect a power supply or battery to the DC- and DC+ terminals. A red LED indicates that power is applied. The evaluation board is made flexible so that the user can disconnect the enable line from the microcontroller and apply external enable signal. External enable signal must be applied to the EN pin. The user interface for the AHK3296 evaluation board is provided by three buttons and two connection terminals. The board is operated by supplying external power and pressing individual buttons or button combinations. When applying external enable signal, consideration must be given to the voltage levels. The externally applied voltage should not exceed the supply voltage that is applied to the IN pins of the device (DC+).
