  • 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.

    In this state-of-the-art boost converter, a DC current path exists between the battery source and the load. In order to reduce the consumption in shutdown mode, a high-side load isolation switch is necessary to cut this DC current path in standby mode. The load disconnect switch (LDS) act as an isolation switch in shutdown mode.

    主な特徴

    • Inductor switches boost controller

    • High efficiency over wide range of load (1 mA to 40 mA)
    • Integrated load disconnect switch
    • Over voltage protection with automatic restart
    • Soft start with adjustable peak current limit
    • Enable pin
    • Low shutdown current
    • Small external inductor
    • Supply voltage from 3.0 V to 5.5 V
