The AHK3293 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 low-drop out voltage current sinks allow the LEDs to operate very close the input supply voltage, eliminating the need for an additional noisy boost power supplies. The AHK3293 requires only one external component, a 1μF ceramic input capacitor (CIN). The AHK3293 can drive three constant output sinks (D1, D2 and D3) each with a maximum current of up to 30.2mA which is set internally. Skyworks' S2Cwire serial interface enables the AHK3293 and changes the current sink magnitude through the EN pin, thereby changing the LED current. S2Cwire Serial Interface The LED output current of the AHK3293 is controlled by Skyworks' S2Cwire serial interface. Since the LED current is programmable, no PWM or additional control circuitry is 8 IREF DAC 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 AHK3293 enters into shutdown mode and draws less than 1μA from the input and the internal data register is reset to zero. The AHK3293 serial interface reduces the LED current on each rising pulse of the enable input. If the AHK3293 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 as shown in Table 1 and Figure 1 for the AHK3293.

LED Selection The AHK3293 is specifically intended for driving white LEDs. However, the device design will allow the AHK3293 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 needing a constant current sink generated from a varying input voltage. Since the D1, D2 to D3 constant current sinks are matched 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 AHK3293 maximize performance and make it capable of driving LEDs with high forward voltages. Multiple 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, the EN input for the AHK3293 should be strobed low for longer than tOFF (500μs). In this state, the AHK3293 typically draws less than 1μA from the input. Registers are reset to 0 in shutdown.

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 Ceramic composition capacitors are highly recommended over all other types of capacitors for use with the AHK3293. 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. Equivalent Series Resistance 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 connec- 10 tions, 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 AHK3293 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.
