GENERAL DESCRIPTION
 The XC9128/XC9129 series are synchronous step-up DC/DC converters with a 0.2Ω (TYP.) N-channel driver transistor and a synchronous 0.2Ω (TYP.) P-channel switching transistor built-in.
A highly efficient and stable current can be supplied up to 1.0A by reducing ON resistance of the built-in transistors.
With a high switching frequency of 1.2MHz, a small inductor is selectable making the series ideally suited for applications requiring low profile or space saving solutions.
With the MODE pin, the series provides mode selection of PWM control or PFM/PWM automatic switching control.
In the PWM/PFM automatic switching mode, the series switches from PWM to PFM to reduce switching loss when load current is small.
When load current is large, the series switches automatically to the PWM mode so that high\ efficiency is achievable over a wide range of load conditions.
The series also provides small output ripple from light to large loads by using the built-in circuit which enables the smooth transition between PWM and PFM.
When a voltage higher than the input voltage is applied to the output during shut-down, the input and the output become isolated making it possible for the IC to work in parallel with the likes of an AC adaptor.

DESCRIPTION
The SP6887 is a 4-channel charge pump white LED driver, capable of driving up to 4 LEDs
connected in parallel.
The device operates in either 1x mode or 1.5x fractional mode, and it can switch from 1x mode to 1.5x mode automatically when the input voltage decreases.

The LED current can be programmed by an external resistor, RSET, connected between the RSET pin and ground.
LED currents of up to 30mA are supported by the input supply voltage over a range of 2.7V to 5.5V, making the device optimized for Li-Ion battery applications.

General Description
 The DM163 is a LED driver that comprises shift registers, data latches, 8x3-channel constant current circuitry with current value set by 3 external resistors, and 64 x 256 gray level PWM (Pulse Width Modulation) function unit.
Each channel provides a maximum current of 60 mA.
The grayscale data are separated into BANK0 and BANK1 respectively, selected by SELBK pin. BANK0 is 6-bits grayscale data and the BNAK1 is 8-bits grayscale data.
Depending on the system requirement, both PWM banks could be utilized jointly to achieve maximum 8+6 bit grayscale performance.
Alternatively, users can choose either 64-graylevel bank or 256-graylevel bank for dot correction, and the remaining bank as image data.
DM163 could also be constructed as a PWM controller for LED drivers.
When VDDH is connected to VDD, each of the 24 output channels outputs can act as an inverse digital signal for controlling the LED driver.
