0936010346, sometimes also known as TPS55601, is a voltage regulator targeting display panel backlight applications. Display panels consume a lot of energy due to their high voltage and current requirements. In order to maintain the optimal power efficiency between the display panel and the power source, voltage regulators are a necessity. TPS55601 is a precision voltage regulator whose application focuses on display panel backlight.

TPS55601 has two main modes of operation – open loop and close loop. In open loop mode, it maintains a constant output voltage to the display panel as long as its input voltage remains within its specified range. This mode is mostly used in LCD, OLED, and LED displays that don’t require very precise voltage regulation. In close loop mode, the output voltage is adjusted for optimal accuracy and control. This mode is more commonly used in LED and plasma displays where precision is important.

The design of TPS55601 allows for maximum flexibility. It can be configured for both positive and negative voltage regulation, as well as pulse width modulation (PWM) control of the output current. This makes it suitable for a wide variety of display panel backlight applications, from high-power automotive displays to small handheld digital imaging devices. Additionally, the TPS55601 is designed for low voltage operation, so it can be used with small Li-ion or coin-cell battery sources.

The TPS55601 leverages digital control of the output voltage using current mode feedback. This feature allows the user to adjust the output voltage without having to physically change any components or wiring. In this way, it can quickly respond to the dynamic requirements of the display panel while providing an accurate and stable output voltage. Furthermore, it also supports Reverse Boost – a process by which the display panel can receive a boost of current during startup before settling down to the correct voltage.

The TPS55601 also supports power saving and protection features. It includes an adjustable undervoltage lockout (UVLO) that can be set to activate under low input voltage, so that no current is drawn when the battery is nearly empty. The TPS55601 also has low standby current mode and a thermal shutdown protection that conserves power at all times. Finally, an external 3-resistors voltage divider network can be used to precisely set the output voltage.

In conclusion, the 0936010346, or TPS55601, is a precision voltage regulator designed to provide the highest efficiency and precision for digital display panels with variable backlighting requirements. The high flexibility and digital control of the TPS55601 along with its low standby current and UVLO settings makes it a great choice for designing the most efficient and stable backlighting systems for any application.
