STOD2540PMR屬于集成電路（IC）的顯示驅(qū)動器。由意法半導(dǎo)體集團制造生產(chǎn)的STOD2540PMR顯示驅(qū)動器顯示驅(qū)動器是一種集成電路 (IC)，可在微處理器 (MPU)、微控制器 (MCU) 或其他電路系統(tǒng)之間提供轉(zhuǎn)換、接口和控制，用于 LCD、LED、OLED、DLP、真空熒光和 AMOLED 等顯示器。可能的通信接口和協(xié)議包括模擬、BCD、I2C、并行、串行、SMBus、SPI 和 QSPI。

描述 Description

STOD2540 is dedicated to passive matrix OLED (PMOLED) displays for portable handsets and provides the pre-charge and biasing voltage of the column matrix driver as shown in figure 3. The current capability of STOD2540 allows feeding a 1, 1.3 or 1.5 color PMOLED. STOD2540 is a boost converter that operates from 3.0 V to 5.5 V and can provide an output voltage as high as 25 V. The output current capability is maximum 40 mA up to 25 V output voltage. The regulation is performed by a resistor divider network (figure 3) that detects the output voltage.
