TPS51219RTET is an extension of TPS51219RT energy transfer (ET) switch mode controller that allows an adjustable output voltage and current setting. It is designed to work as an integrated power supply (IPS) switch mode controller ensuring an optimized power saving solution. This device operates in an adjustable frequency discontinuous conduction mode, boosting efficiency in relation to the required output power.

The TPS51219RTET provides the following features to assist in the design of power efficient products, including high efficiency Transfer Mode (TM) and Discontinuous Conduction Mode (DCM) switching, input power feed-forward capability, multi-phase current balancing and a low-power stand-by mode.

The TPS51219RTET is designed to be used in a wide range of applications, especially where many power sources are used such as laptop and tablet PCs, mobile phones, digital cameras and HD video players. In particular, this device offers very competitive efficiency for multi-channel systems where multiple voltage rails derived from a single power source are necessary.

This device, thanks to its sophisticated control logic and features, is a very effective solution for powering systems robustly and efficiently. By employing this device in a system, overall cost and design time are reduced, while the efficiency and reliability of the system are improved.

The working principle of the TPS51219RTET is very straightforward and allows for high speed operation. It employs a high current and low voltage switch mode power converter, which supplies a regulated controlled output voltage. The two outputs of the converter are connected to two inductors, allowing any surplus energy to be stored in the inductor instead of dissipating it in the output load.

The high side switch is internally regulated, while the low side switch is externally regulated by an adjustable DC/DC converter. The TPS51219RTET supports multiple voltage ranges and provides adjustable output voltages. It also supports various current limiting settings to protect the system against overloads or excessive currents.

The TPS51219RTET is designed to be extremely energy efficient and requires very low current drain from the input power source. By optimizing the processor and its associated system components for each application, power savings of up to 50% can be achieved. This allows for efficient and cost effective solutions.

The TPS51219RTET is an excellent device for power management applications where high efficiency and low cost solutions are required. It is an ideal choice for modern electronic products like tablets, notebooks and PDAs that require efficient and cost-effective power solutions.
