TPS62054DGSG4 is a 4MHz 3V-6V wide input range, synchronous step-down DC/DC converter with integrated FETs, termed as Power Module (PM), which been designed to provide optimized power conversion in an ultra-compact solution size. It also features adjustable output voltage by external resistor, over current protection, output disconnect, over temperature protection, and low quiescent current.

Application Field

The TPS62054DGSG4 is a new generation DC-DC power module with integrated FETs and a wide input voltage range of 3V to 6V. This type of DC-DC module is used for applications such as power management in industrial automation, LED lighting, solar or wind power systems and electric vehicles.

The versatility of the TPS62054DGSG4 comes from its wide input voltage range, adjustable output voltage, robust protection features and low quiescent current. The module is optimized for minimum board size, allowing for compact designs that integrate easily into existing architectures, helping engineers to reduce their overall design cycle time and cost.

With its wide input voltage range, the TPS62054DGSG4 can be used in a variety of applications where a wide range of input power sources is required. The module\'s integrated FETs provides more than 5A output current, reducing the need for external components and enabling efficient power conversion with low power loss.

Working Principle

The TPS62054DGSG4 DC/DC power module utilizes synchronous rectification to deliver high efficiency at all load levels. The chip integrates high-side and low-side FETs and uses Pulse Width Modulation (PWM) to regulate the output voltage. In the off-time mode, the FETs are turned off, the voltage is reduced to zero, the input current is disconnected and no power is dissipated. In pulse-width modulation mode, the voltage across the switching elements is controlled using the PWM signal, while the FETs can be switched on or off depending on the output voltage level.

The module also features adjustable output voltage. Using an external resistor, the output voltage can be set to maximum of 6V. The output voltage is then regulated by the on/off current flow in the FETs, allowing for extra flexibility when setting the output voltage. The module also features over-current, temperature and output disconnect protection, as well as an automatic switch off when the input voltage is too low.

The TPS62054DGSG4 is ideal for applications that require a wide input voltage range, adjustable output voltage and robust protection features. The module\'s low power loss, low quiescent current, and small size make it an attractive solution for applications such as power management in industrial automation, LED lighting, solar or wind power systems and electric vehicles.
