PMIC - Voltage Regulators - DC DC Switching Regulators

The LTC1911EMS8-1.8#PBF is a high performance DC-DC switching regulator ideal for powering onboard semiconductor, field-programmable gate array (FPGA) and other high performance systems. The LTC1911EMS8-1.8#PBF consists of three stages: an error amplifier, a control circuit and a synchronous P-channel MOSFET (PMOS) switch. It provides excellent load and line regulation, as well as low ripple and noise. The LTC1911EMS8-1.8#PBF is also well suited for applications that require wide input voltage range and high conversion ratio up to 45V to 20V.

Application Field

The LTC1911EMS8-1.8#PBF is typically used in providing the necessary voltage to supply an FPGA, ASICs, or any other high-performance devices. It can be used in industrial, telecom, consumer, automotive, aviation and space industries. Furthermore, the LTC1911EMS8-1.8#PBF can be used to provide a safe and efficient voltage for DSPs, FPGAs, ASICs, memory, processors and power management ICs used in smartphones, tablets and other mobile devices.

Working Principle

The LTC1911EMS8-1.8#PBF employs the industry’s smallest die size, which helps to significantly reduce overall power circuit size and significantly reduce cost of power conversion system. This switching regulator is based on an error-amplifier control scheme, which enables the system to keep accurate variables such as output voltage, line and load regulation, ripple and noise.The control circuit within the LTC1911EMS8-1.8#PBF uses the error-amplifier circuit to compare the voltage on the feedback pin with the internal reference voltage of 1.25V, and then adjust the duty cycle of the internal PMOS switch accordingly to provide voltage conversion. The PMOS switch is then activated and synchronously turned on and off to transfer energy directly from the input source to the output. This ensures greater efficiency, lower ripple and noise, increased power delivery efficiency and stable output voltage.The LTC1911EMS8-1.8#PBF also includes other features such as soft start, light load mode, input voltage monitoring, and over-voltage protection. These features help optimize the LTC1911EMS8-1.8#PBF for better operation and performance.

Conclusion

The LTC1911EMS8-1.8#PBF is a high performance DC-DC switching regulator ideal for providing necessary voltage to supply an FPGA, ASICs, DSPs, FPGAs, ASICs, memory, processors and power management ICs. It features excellent load and line regulation, low ripple and noise, wide input voltage range, and high conversion ratio up to 45V to 20V. The LTC1911EMS8-1.8#PBF is an ideal solution for powering onboard semiconductor, field-programmable gate array (FPGA) and other high performance systems in industrial, telecom, consumer, automotive, aviation and space industries, as well as mobile devices.
