Introduction
FPF1005 is a power distribution switch, load driver and System Power Management IC (PMIC) all in one chip developed by Fairchild Semiconductor. The device integrates a low-loss Power FET and a current-limited switch controller on-chip, providing a high level of integration and board-level design flexibility. The FPF1005 also offers active-low shutdown, leading edge blanking (LEB) and Constant On-Time (COT) control modes, giving designers flexibility in their system power management requirements.Features
The FPF1005 offers a wide range of features that make it ideal for system level power management designs. The main features of the device are as follows.- Low Loss Power FET: The Power FET in the FPF1005 has a low on-resistance of 0.12Ω at 25°C, which contributes to low power dissipation.- Efficiency Boost: The constant on-time control mode increases efficiency and reduces board size.- Thermal Protection: The internal thermal protection circuitry prevents damage caused by excessive temperatures.- Flexible Voltage Range: The FPF1005 offers an adjustable output voltage range from 0.8 V to 6 V.- 48V Load Drive: The high-side gate drive allows for driving up to 48V loads.Application Areas
The FPF1005 can be used in a variety of applications, including distributed power systems, communications, computing, consumer electronics and automotive systems. The device is especially well-suited for applications such as multiple supply rails, high-side switches, power DIMMs, CPUs, DC-DC converters, LCD displays and GPUs. The features of the device make it an ideal choice for high-current, high-speed switching, where switching losses and EMI noise can be reduced.Working Principle
The FPF1005 works on the principle of Constant On-Time Switching. In this mode, the output voltage of the device is controlled by the switching cycle time. The switching cycle time is determined by an external resistor and capacitor connected to the Oscillator Input pin (OSC_IN).The switching cycle starts when the OSC_IN voltage rises above the threshold voltage, which triggers the switch to turn on. The ON-time is determined by the capacitor, and the OFF-time is determined by the internal current-limit protection circuit. This ensures that the device operates within its thermal limit and does not require a large heat sink.The output voltage can be further fine-tuned by adjusting the current-limit value of the external resistor connected to the OSC_IN pin. The switching frequency is automatically adjusted by the device depending on the load conditions, ensuring that the output voltage is maintained at the desired level.Conclusion
The FPF1005 is an integrated PMIC that integrates a low-loss Power FET and current-limited switch controller on-chip. It offers a wide range of features and benefits, making it an ideal choice for system level power management designs. The device offers active-low shutdown, leading edge blanking and Constant On-Time (COT) control modes, allowing designers to customize their system power management requirements. The device is suitable for a variety of applications, ranging from distributed power systems to consumer electronics.
