Wide input voltage

The TPS 65136 is designed to provide best-in-class image quality for active matrix OLED (AMOLED) displays that require positive and negative power supply rails. Due to its wide input voltage range, it is ideal for AMOLED display and can be used for mobile phones and SmartPhone ™ devices. The new single inductor multiple output (SIMO) technology enables the smallest solution size. The device features a buck-boost topology that generates positive and negative output voltages above and below the input voltage rail. SIMO technology enables superior line regulation and load regulation. Excellent line transient regulation is necessary to avoid interference with the AMOLED display due to input voltage fluctuation occurring during the transmission cycle of the mobile communication system

Power supply units are classified in various ways, including functional characteristics. For example, a regulated power supply is a power supply that maintains a constant output voltage or current under variations in load current or input voltage. Conversely, the output of an unregulated power supply can change significantly as its input voltage or load current changes. Using an adjustable power supply, you can program the output voltage or current with mechanical control (such as a knob on the front panel of the power supply) or control input, or both. Adjustable adjustable power supply is adjustable and regulated power supply. The power output of an isolated power supply is independent of the power input; this is in contrast to other power supplies sharing the connection between the power input and the output.

The DC power supply uses AC power as the energy source. This power supply uses a transformer to convert the input voltage to a higher or lower AC voltage. A rectifier is used to convert the output voltage of the transformer to a varying DC voltage that passes through an electronic filter and converts it to an unstabilized DC voltage. This filter eliminates the majority (not all) of the change in AC voltage and the remaining AC voltage is called ripple. The ripple tolerance of the electrical load determines the minimum amount of filtering that the power supply must provide. Depending on the application, high ripple is allowed, so filtering is unnecessary. For example, in some battery charging applications, it is possible to implement a power supply DC power supply with only a transformer and a single rectifier diode, connecting a resistor in series with the output to limit the charging current.
