Introduction to TPS61282YFFRTPS61282YFFR is a complete DC-DC step-down converter with integrated MOSFETs, manufactured by Texas Instruments (TI). This highly efficient, cost-effective device was created for powering distributed load systems and multi-power-domain applications in automotive, industrial, and computing electronics. This robust voltage regulator offers a wide input voltage range, fast transient response, and superior noise immunity.Application Field and Working PrincipleTPS61282YFFR is designed for powering multiple power domains with a single solution capable of reaching the highest power efficiency from an input voltage range of 4.5V to 17V. This device is ideal for complex distributed-load systems and multiple power-domain applications for automotive and industrial electronics, such as motor drives, robotics, building automation, and HVAC. The TPS61282YFFR works by using a fixed frequency synchronous PWM converter to maintain a regulated output voltage. It has an integrated circuit driver which allows the user to control and monitor the switch, along with programmable soft-start and ramp times. The maximum duty cycle of this device is 95.5%, allowing it to remain highly efficient. The device also has an internal duty cycle limiter that protects it from current overloads and limits the peak switch current to 500mA. This overload protection helps maintain power system stability and reduce losses in real-time. The internal output voltage range of the TPS61282YFFR is adjustable from 0.6V to VIN, allowing for flexibility in its design and application. The integrated MOSFETs help to reduce external components, decreasing the overall design complexity and cost. This device also has integrated overcurrent protection and thermal shutdown, further increasing its robustness and reliability. ConclusionThe TPS61282YFFR is a highly efficient, cost-effective DC-DC converter that makes it ideal for distributed load systems and multiple power-domain applications in automotive and industrial electronics. This voltage regulator has a wide input voltage range, fast transient response, and superior noise immunity, which makes it suitable for a variety of scenarios. The integrated MOSFETs and its fixed frequency synchronous PWM converter help to reduce external components, design complexity, and cost while increasing efficiency and reliability.
