TS3410CX5 RFG

PMIC - Voltage Regulators - DC DC Switching Regulators

The TS3410CX5 RFG is an ultra-compact buck-boost DC/DC power converter specifically developed for the Chinese market. Developed by Trellis System, the TS3410CX5 RFG is housed in a Type 1 plastic package and enables buck-boost operations from a wide input voltage range of 2.5 V to 17 V. Its integrated control circuitry and internal power MOSFETs make it highly efficient, allowing it to deliver up to 4.5 A of continuous output current.

The TS3410CX5 RFG is designed to provide a regulated, adjustable output voltage that can range between 0.8 V and 5 V. Its adjustable output voltage is controlled by an external resistor divider, allowing designers to select the desired voltage output value and thus fine-tune their systems. Furthermore, the TS3410CX5 RFG is equipped with a current limit and over-temperature protection features, which help ensure safe operation.

The TS3410CX5 RFG from Trellis System is suitable for a wide range of applications, such as powering FPGAs, powering and/or charging electronic devices, powering processors and transceivers, etc. Its ultra-compact package is also ideal for devices that require minimal space, such as portable and wearable electronics, as well as IoT applications.

Working Principle

The TS3410CX5 RFG is a boost-type DC/DC converter. When it is powered up, it begins by operating the internal switching MOSFETs in an ON/OFF sequence to generate a voltage rise beyond that of the input voltage. The switch-mode regulator then applies a PWM (pulse-width modulation) signal on the switching MOSFETs to provide a more accurate and constant output voltage.

The TS3410CX5 RFG utilizes an internal multiple loop-control architecture. It controls the output voltage by modulating the duty cycle of the PWM signal. The integrated control circuit ensures high accuracy and stable output voltage. Furthermore, the TS3410CX5 RFG features an integrated current-mode control, which provides better line and load regulation as well as transient response characteristics.

To ensure safe operation, the TS3410CX5 RFG features over-current and over-temperature protection. The over-current protection shuts down the converter when the input over-current is exceeded, and the over-temperature protection switches off the converter when its internal components reach a certain temperature. The TS3410CX5 RFG also supports auto-restart mode, allowing it to automatically restart after the over-current or over-temperature condition has been cleared.

In summary, the TS3410CX5 RFG is a versatile, reliable and highly efficient buck-boost switching DC/DC converter designed to provide adjustable output voltages over a wide input voltage range.
