The AHK3292 operates directly from a 2.7V to 5.5V power source and enables and controls the currents to the diodes. Both channels are individually controlled through integrated current sinks powered from an external power supply. Low resistance and low-dropout voltage current sinks allow the LEDs to operate very close to the input supply voltage, eliminating the need for an additional boost power supply. The AHK3292 requires only two external components: one 1μF ceramic input capacitor (CIN), and a resistor (RSET) to set the maximum LED current. The AHK3292 can drive two constant output sinks, D1 and D2, up to 30.2mA maximum current each. Skyworks' S2Cwire serial interface enables the AHK3292 and changes the current sink magnitude through the EN pin. S Cwire Serial Interface 2 The LED output current of the AHK3292 is controlled by Skyworks' S2Cwire serial interface. Since the LED current is programmable, no PWM or additional control circuitry DAC IREF GND RSET 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 “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. The S2Cwire interface relies on the number of rising edges to the EN/SET pin to set the register. A typical write protocol is a burst of EN rising edges, followed by a pause with EN held high for at least tLAT (500μs). The programmed current is then seen at the current sink outputs. When EN is held low for an amount of time longer than tOFF (500μs), the AHK3292 enters into shutdown mode and draws less than 1μA from the input and the internal data register is reset to zero. The AHK3292 serial interface reduces the LED current on each rising pulse of the enable input. If the AHK3292 is in shutdown, the first rising edge of the EN input turns on the LED driver to the maximum current. Successive rising edges decrease the LED current according to Table 1 and Figure 2.

As an example, a single LED can typically be driven at 60.4mA total by combining together the D1-D2 outputs as shown in Figure 3. LED Selection The AHK3292 is specifically intended for driving white LEDs. However, the device design will allow the AHK3292 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 D2 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 AHK3292 maximize performance and make it capable of driving LEDs with high forward voltages. The two channels can be combined to obtain a higher LED drive current without complication. Capacitor Selection 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 it. If the constant current sinks are only programmed for light current levels, then the input capacitor size may be decreased. Capacitor Characteristics Shutdown Ceramic composition capacitor is highly recommended over all other types of capacitors for use with the AHK3292. 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 nonpolarized. Since ceramic capacitors are non-polarized, they are not prone to incorrect connection damage. 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, the EN input for the AHK3292 should be strobed low for longer than tOFF (500μs). In this state, the AHK3292 typically draws less than 1μA from the input. Registers are reset to 0 in shutdown. VIN CIN 1μF IN AHK3292 EN EN/SET RSET 9.53kΩ RSET GND D1 D2 Figure 3: Higher Current Single LED Application.

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. 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 AHK3292 applications. Capacitor area is another contributor to ESR. 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 The user interface for the AHK3292 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. Table 3 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. 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+).
