TPS53014DGSR Integrated Circuits (ICs)

Introduction

TPS53014DGSR is an advanced, high current, high frequency synchronous step-down DC/DC controller with configurable input voltage range, operating temperature and output power from 0.7V/1.05V input voltage range, -40 to 85°C temperature range, and 5A/9A of output power. With the TPS53014DGSR, designers can accurately achieve the exact output voltage and current that the load requires for the load application in a small form factor.

The integrated Flexible Gate Pulse Trim technology enables precision programming of the switching frequency to minimize EMI and minimize the solution size. The combination of the wide operating voltage range, with the high switching frequency, provides a compact and robust solution for industrial and automotive applications.

Application Field

One of the main applications of the TPS53014DGSR is power conversion in automotive components, offering a wide range of input and output voltages, ensuring low total harmonic distortion (THD) over a broad range of input and output voltages, and wide adjustment range of output voltage. This contribution makes the TPS53014DGSR an ideal choice for efficient power conversion such as digital power supplies, step-down buck converters, voltage-mode regulation and load sharing applications.

The wide input voltage range and integrated Flexible Gate Pulse Trim (FGPT) also make the TPS53014DGSR suitable for computing and board-level applications, such as PCs and peripherals, notebooks, notebooks adapters, displays, base stations and wireless communication systems.

Working Principle

The TPS53014DGSR integrates a high current, high frequency synchronous step-down DC/DC controller. The TPS53014DGSR is a current-mode, synchronous, step-down converter, offering maximum efficiency, high line/load regulation and fast transient response. The device incorporates a single-stage synchronous buck controller. The converter is controlled by a fixed frequency current mode control. Two high-side power MOSFET drivers are provided, with input voltage range from 0.7V to 1.05V.

Furthermore, the TPS53014DGSR also incorporates an adaptive on-time slice regulator and adjustable step-up/down capabilities for higher efficiency monitoring and maximum flexibility. The integrated Gate Pulse Trim (GPT) provides programmable gates for both MOSFETs, enabling precise adjustments of the switching frequency to minimize the solution size. Moreover, the on-time regulator also provides precise control of the output, with fast transient response.

Additionally, the TPS53014DGSR also possess comprehensive protection features such as cycle-by-cycle current limit, and output over-voltage protection, with both over-temperature and undervoltage protection to ensure long-term system stability under harsh environments.
