S6B0717X01-XXXN datasheet

Description

The S6B0717 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 55 common and 100segment driver circuits. This chip is connected directly to a microprocessor, accepts serial or 8-bit parallel display data and stores in an on-chip display data RAM of 65x 100bits.It provides a high-flexible display section due to 1-to-1 correspondence between on-chip display data RAM bits and LCD panel pixels. And it performs display data RAM read/write operation with no external operating clock to minimize power consumption.

components

In addition, because it contains power supply circuits necessary to drive liquid crystal, itis possible to make a display system with the fewest components.

LM25085 datasheet

 

Description

The LM25085 is a high efficiency PFET switching regulator controller that can be used to quickly and easily develop a small, efficient buck regulator for a wide range of applications. This high voltage controller contains a PFET gate driver and a high voltage bias regulator which operates over a wide 4.5V to 42V input range. The constant on-time regulation principle requires no loop compensation, simplifies circuit implementation, and results in ultra-fast load transient response.

The operating frequency remains nearly constant with line and load variations due to the inverse relationship between the input voltage and the on-time. The PFET architecture allows 100% duty cycle operation for a low dropout voltage. Either the R DS(ON) of the PFET or an external sense resistor can be used to sense current for over current detection.
