TDE1787DP is an integrated, high-performance, low-dropout (LDO) bipolar regulated power converter device. With the ability to source up to 2.2 A of continuous output current into a wide variety of load configurations, it is ideally suited for powering the latest technologies, from digital cameras to smart phone devices and beyond. The architecture of the TDE1787DP, combined with its low quiescent current, dynamic mode control, and efficient switching converter technology, makes it an excellent solution for applications requiring high-efficiency power conversion.

The TDE1787DP is a PMIC Power Distribution Switch, Load Driver and System-on-Chip (SoC) device, designed to reduce the power management complexity in applications that require multiple power domains to be sequentially enabled, synchronized, and controlled with ease. The device integrates a high-resolution gate driver, ultra-low quiescent current regulator, and adjustable current limit, designed to provide scalable voltage and current regulation with dynamic transient response. The TDE1787DP regulates two independent outputs for two devices or Chipsets, making it an ideal solution for powering digital cameras, VoIP phones and other mobile devices.

At the heart of the TDE1787DP is its digital power management, which allows for independent control and monitoring of two devices or chipsets. The device offers a synchronous buck-boost converter, high resolution voltage and current monitoring, and adjustable current limit along with programmable slew rates. Its integrated high-frequency gate drivers provide low output noise, fast device response times, and increased efficiency. The low output noise also helps reduce EMI and reduces interference with other connected circuits.

The TDE1787DP\'s buck-boost converter allows it to quickly switch between VOUT and VIN ranges. By using the adjustable current limit function, the current limit can be set to ensure proper device and system protection from over-current scenarios. The device also includes a peak current limit feature, and a reference current limit, which helps provide a safe operating range for current regulation.

The device\'s robust design is protected by various safety and EMI protections, such as over-temperature, over-voltage, under-voltage, and current limit protections. Additionally, the TDE1787DP features an output OVP alarm, and a soft-start circuit to provide a controlled start-up of the outputs.

The TDE1787DP\'s advanced architecture also offers some peripherals and communications, such as SMBus and I2C. These communications allow the system to send and receive real-time information through a communications link, redistributing information within the system and allowing for increased system monitoring and control.

The TDE1787DP is the ideal solution for high power and multi-port, multi-voltage applications, offering the highest system performance with complete safety and reliability. Its low-profile design, wide operating temperature range, and adjustable current limit provide reduced power consumption, improved reliability, and optimized system performance.
