Analog Devices has unveiled the LT7182S, a breakthrough in power management technology. This dual-output monolithic PolyPhase DC-to-DC synchronous step-down regulator boasts impressive capabilities, delivering up to 6A of continuous current from each channel while supporting loads of up to 8A from either channel.
The LT7182S incorporates the innovative second-generation Silent Switcher architecture, setting a new standard for efficiency and performance. By integrating VIN bypass capacitors, it ensures fast, clean switching edges with minimal overshoot, even at high switching frequencies. This not only maximizes efficiency but also minimizes electromagnetic interference (EMI) emissions, contributing to cleaner power delivery.
A notable application of the LT7182S is demonstrated in circuit DC2836A, a dual-output PolyPhase DC/DC synchronous step-down regulator with an input range of 4V to 20V. Leveraging the LT7182S, this circuit showcases the benefits of second-generation Silent Switcher technology, including reduced EMI and decreased sensitivity to PCB layout.
Furthermore, the LT7182S integrates digital power system management functionality, allowing for programmability and telemetry via a PMBus/I2C compliant serial interface. This feature enhances flexibility and control, enabling precise adjustment of power delivery parameters to suit various system requirements.
In conclusion, Analog Devices' LT7182S represents a significant advancement in power management technology. Its dual-channel design, coupled with PolyPhase architecture and Silent Switcher 2 technology, delivers high efficiency, low EMI emissions, and enhanced control capabilities, making it a versatile solution for a wide range of applications.
