PMIC - Voltage Regulators - DC DC Switching Controllers

The TLE63893GV50XUMA2 is a DC-DC switching controller with an integrated MOSFET, from Infineon Technologies. It belongs to the family of voltage regulators, which provide a steady supply voltage for a wide range of applications. It is a single-phase push-pull controller for synchronous buck converters.

The TLE63893GV50XUMA2 is specifically suited to applications that require a reliable, efficient and accurate supply of power. These include data storage and communication systems, automotive, industrial control, servers and high-end televisions. It is designed for a wide operating temperature range and delivers high energy efficiency, ensuring reliable operation of the system.

Working Principle

The TLE63893GV50XUMA2 utilizes pulse width modulation (PWM) to regulate the output voltage. The PWM is a two-model system, in which one model switches the power FET on and off, while the other adjusts the duty cycle to control the output voltage. This pulse-width control is used to reduce losses in the converter and provides high energy efficiency. To avoid output voltage instability, the TLE63893GV50XUMA2 has an active current limitation and over temperature protections.

The device contains integrated protection blocks with soft-start, short circuit and overtemperature protection, as well as overcurrent, under voltage and over voltage protection. The embedded features of the controller provide lower total system cost and reduced development time. The TLE63893GV50XUMA2 can operate at a frequency of up to 1.2 MHz, enabling fast transient response and excellent line and load regulation. The starting switching frequency is adjustable from 200 kHz to 600 kHz.

Advantages

The TLE63893GV50XUMA2 DCDC controller has a number of advantages compared to other traditional voltage regulators. Its integration of a MOSFET enables a small PCB layout, allowing flexible and space-saving designs. It is designed to withstand extreme ambient temperatures and has a high level of accuracy, providing reliable power delivery. The controller also has low output ripple, which enables fast transient response, a wide input voltage range and good line and load regulation.

The TLE63893GV50XUMA2 features an external compensation network with a low bandwidth, which reduces design time and complexity.
