DC DC Switching Controllers datasheet and documents for TPS5120DBT
DC DC Switching Controllers Overview
The TPS5120DBT is a dual-output, two-phase synchronous buck controller manufactured by Texas Instruments. It operates with a switching frequency range of 100 kHz to 500 kHz and supports a maximum duty cycle of 83%. The device regulates output voltages between 900 mV and 26 V, capable of driving loads up to 20 A. It functions within an operating temperature range of -40°C to +85°C and consumes 1.1 mA of supply current. The component is housed in a 30-pin TSSOP package designed for surface mount installation.
DC DC Switching Controllers Feature Summary
- Dual-channel architecture providing independent control with 180-degree phase shift to minimize input current ripple
- Configurable PWM or skip mode operation to optimize efficiency under light load conditions
- Integrated high-side and low-side MOSFET drivers eliminating the need for external resistors
DC DC Switching Controllers Applications
- High-performance computing systems requiring multi-rail power distribution
- Telecommunications infrastructure equipment
- Industrial automation controllers
DC DC Switching Controllers Procurement Notes
Verify the specific suffix DBT corresponds to the tube packaging configuration when ordering. Confirm that the standard commercial temperature grade meets the operational requirements of the target environment. Ensure compatibility with the intended PCB footprint for the 30-pin TSSOP package before finalizing procurement specifications.
DC DC Switching Controllers Selection Notes
Select this controller for designs requiring two independent synchronous buck outputs from a single IC. It is suitable for applications needing flexible sequencing via external soft-start capacitors. Consider the 20 A output capability and wide input voltage range when sizing external components for the specific power delivery requirements.
DC DC Switching Controllers Part Context
This component belongs to the TPS5120 series of synchronous buck controllers. It is part of Texas Instruments' portfolio of power management integrated circuits focused on efficient DC-DC conversion. The device complements other PMIC solutions by offering a compact, high-efficiency approach to powering complex digital loads.
DC DC Switching Controllers Replacement Considerations
The TPS5120QDBTREP is a qualified automotive-grade variant within the same family. Verify if extended temperature ranges or specific reliability standards are required before substituting.
