Application Field
The TPS53661RSBR is ideally suited for FDI, FIVR, Core X-Series, memory, server, and storage applications. It has a wide input voltage range, a wide output voltage range, fast transient response, and excellent efficiency. It is suitable for applications that require low output voltages and excellent transient response. It is also suitable for applications that require sensitive voltage detection, such as process control and communications.
Working Principle
The TPS53661RSBR synchronous buck converter is designed to support multiple output voltages. It uses voltage feedback via its two internal voltage feedback pins, VFB1 and VFB2, to regulate output voltage. The output voltage can be set via external resistors, allowing for a wide range of output voltages. Apart from voltage feedback control, it also incorporates current mode control and adaptive on-time control, giving the converter fast transient response and excellent efficiency.
The device integrates the high and low side FET drivers, and the N-channel MOSFETs. The high side and the low side MOSFET drivers are driven by a single gate driver, which is triggered by the PWM controller. The PWM controller provides the PWM signal for the high and low side drivers. The PWM control converges the current mode and adaptive on-time control synchronous buck control to ensure fast regulation and optimal efficiency.
The device also has multiple protection features, such as over current protection and over temperature protection, providing a safe and reliable operation. The device also has separate enable pins for the main and LDO enable and a separate source enable pin. This makes it easier to design and provides increased versatility and safety for the device.
Conclusion
The TPS53661RSBR is a high-efficiency and high-performance synchronous buck regulator with dynamic voltage identification (VID) suitable for Intel FDI, FIVR, Core X-Series, memory, server and storage applications. It is designed to be safe and robust, with just a few external components needed for easy design, fast startup, accurate and fast response to changes in load, and excellent efficiency. It features a wide input voltage range, a wide output voltage range, and fast transient response. It also incorporates multiple protection features, such as over current protection and over temperature protection, providing a safe and reliable operation.
